If you’re battling loose or stripped bolts on your Black+Decker miter saw, the ZTTM 2-pack of 145344-01 replacement blade bolts delivers a no-nonsense fix with precision fit and rugged simplicity. Engineered specifically for models like the 1710 and 3660 series, these bolts feature a 1/2″ hex head and M8 threading, ensuring secure blade retention during high-RPM cuts. The left-hand thread design is a standout—it counters rotational forces that typically loosen standard bolts, drastically reducing the risk of blade slippage and enhancing job-site safety.
In real-world use, these bolts install smoothly with a standard wrench, holding firm even after repeated blade changes and heavy-duty crosscuts. They’re built to handle the vibrational stress common in older Black+Decker saws, and their compact 1″ length ensures proper arbor alignment without overextending. While they lack the forged strength of premium-grade steel, they perform reliably for DIYers and light contractors. However, users with DeWalt or Craftsman saws should look elsewhere—this bolt is strictly for Black+Decker compatibility and won’t fit other brands.
Compared to universal aftermarket options, the ZTTM 145344-01 bolts shine in model-specific reliability. They’re not flashy, but they solve a critical pain point: a wobbling or dislodged blade. For owners of aging Black+Decker miter saws, this two-pack offers peace of mind and a quick, cost-effective refresh. When stacked against the OZXNO N600011 pack, it trades broader compatibility for exact-match precision, making it ideal for users who want OEM-level assurance without the OEM price.

Slight thread variance reported
The OZXNO N600011 miter saw blade bolt is a game-changer for DeWalt users who demand safety, strength, and smart engineering in a small but critical component. Featuring a left-hand thread design, these bolts resist loosening under the intense torque of high-speed blade rotation—a common failure point in many compound miter saws. Crafted from corrosion-resistant metal with a 1.06″ length and 0.3″ thread diameter, they’re built to endure job-site conditions while maintaining a snug, wobble-free fit on models like the DWS716XPS, DWS779, and DCS361M1.
During testing, the bolts installed cleanly with minimal effort and held firm through repeated bevel and crosscut operations. The flange-style head acts as an integrated washer, distributing pressure evenly and preventing damage to the blade hub—something cheaper bolts often overlook. They handled the vibration of a DWS779 flawlessly, even after dozens of blade changes. While they’re not rated for extreme industrial use, they’re more than capable for contractor-grade work. One minor limitation: the package doesn’t include a wrench, so you’ll need a 7/16″ hex tool on hand.
Against competitors like the CHENJIN 3-pack, the OZXNO stands out with superior material quality and targeted DeWalt compatibility. It’s not the cheapest option, but it delivers where it counts: safety and reliability. For users who prioritize long-term durability over bulk quantity, this 2-pack offers a smarter investment than generic multi-packs. It’s the kind of part you forget about—in the best way—because it just works, every time.

For DeWalt miter saw owners tired of juggling loose bolts and mismatched tools, this combo pack of N600011 blade bolt and N600007 wrench is a brilliantly practical solution. The left-hand threaded bolt ensures your blade stays locked down under high-speed operation, while the included 7/16″ hex wrench is perfectly sized for quick, tool-free changes. Together, they eliminate the frustration of hunting for the right socket or risking slippage with ill-fitting tools—a small upgrade that transforms your workflow.
In real-world use, the bolt fits snugly on models like the DWS716, DWS780, and DHS790T2, with the flange head providing even pressure and preventing washer loss. The wrench is forged from hardened steel, resisting rounding even when torque is applied—critical when dealing with a seized or over-tightened bolt. Both components are built to last, with a corrosion-resistant finish that holds up in humid or dusty environments. The only downside? The wrench is specific to this bolt type, so it won’t replace a full socket set, but that’s the trade-off for precision optimization.
Compared to buying parts and tools separately, this combo offers exceptional value and convenience. It’s especially ideal for users who frequently change blades or work in remote job sites where tool access is limited. While the ZTTM pack offers more bolts, this set wins with integrated functionality. It’s not just a replacement—it’s a workflow upgrade, pairing reliability with ease of use in a way few accessory kits manage.

When you need bulk replacement bolts without breaking the bank, the CHENJIN 3-pack of 648697-00 blade bolts delivers affordable reliability for a range of DeWalt and compatible saws. These non-OEM but OEM-spec bolts are forged from durable materials and rigorously tested to ensure they meet the dimensional and strength requirements of models like the DC310K, DCS372B, and DC390 series. With a compact, sturdy build and smooth threading, they install easily and hold firm under normal operating conditions.
In practice, these bolts perform well for DIYers and occasional users who need spares on hand. They’re resistant to stripping and maintain integrity through multiple installations, thanks to their hardened construction. The 3-pack offers excellent redundancy, ensuring you’re never stranded mid-job with a damaged bolt. However, they lack the left-hand thread design found in higher-end models, making them less ideal for high-torque saws where rotational force can loosen standard threads. They’re best suited for lighter-duty applications or backup use.
Compared to the OZXNO N600011, the CHENJIN bolts trade advanced safety features for quantity and cost efficiency. They’re not the best choice for heavy contractors, but for homeowners or hobbyists maintaining older saws, they offer a smart, budget-conscious solution. If you’re looking for a long-term, high-performance fix, go premium. But if you want three solid spares that won’t fail when needed, this pack hits the mark.

The only downside: its premium build comes with a steeper price, though the 2-pack helps offset long-term costs.
Against the CHENJIN 3-pack, this bolt is in a different league—engineered for performance, not just function. It’s the ideal choice for contractors who’ve experienced bolt failure and want a bulletproof solution. When compared to the genuine Craftsman OEM bolt, it offers superior material strength and safety design, making it the best pick for users who refuse to compromise on durability.

How to Choose the Right Craftsman Miter Saw Blade Bolt
When replacing a miter saw blade bolt, especially for Craftsman or compatible models, it’s important to choose the right part for safety, performance, and compatibility. The wrong bolt can lead to blade slippage, unsafe operation, or damage to your saw. Here are the key features to consider when selecting the right miter saw blade bolt.
Check Compatibility with Your Saw Model
Always confirm the bolt fits your specific miter saw model.
Different brands and models use different part numbers—common ones include 145344-01 for DeWalt and 648697-00 for newer Craftsman or Black+Decker saws.
Using an incompatible bolt can cause improper fit and safety hazards.
Refer to your owner’s manual or product label to verify the correct part number.
Choose the Correct Thread Type: Left-Hand Thread is Critical
Miter saw blade bolts use a left-hand thread to prevent loosening during operation.
Since the blade spins clockwise, a standard right-hand thread would gradually unscrew itself.
A left-hand thread tightens under rotation, keeping the blade secure.
Ensure your replacement bolt has this reverse thread design—most quality replacements clearly state this feature.
Prioritize Material Quality and Durability
Look for bolts made from high-grade steel (like 12.9 grade) with a black oxide or corrosion-resistant finish.
Strong materials resist wear, stripping, and rust, especially under heavy use.
A flanged bolt design acts as a built-in washer, improving grip and stability.
Avoid low-quality or unbranded bolts that may strip or fail under pressure.
Consider Package Quantity and Value
Some packs include 2–3 bolts, which is useful for having spares.
Frequent users or professionals benefit from multi-packs (like 3-pack options) to avoid downtime.
Bulk or multi-packs often offer better value than single replacements.
Include a Wrench if Needed
Some kits come with a matching wrench (like the N600007), which ensures you have the right tool for installation.
Using a worn or incorrect wrench can damage the bolt head.
A combo kit saves time and ensures compatibility between tools and hardware.
Always install the bolt properly using the correct torque—over-tightening can damage threads, while under-tightening risks blade movement. Safety first: replace worn, stripped, or damaged bolts immediately.
