Why Quality Knife Hardware Matters
The performance of any knife — folding or fixed — depends heavily on the quality of its hardware. Inferior screws can strip, washers can warp, and poor-quality bearings create rough, unreliable action. Our hardware is sourced from premium materials including 416 stainless steel (prized for its machinability and corrosion resistance) and solid brass (favored for its smooth bearing surface and classic look). Whether you need M3.5 or M4 thread sizes, T8 Torx drive patterns, or custom-fit gasket washers for specific knife models like the BM535 or BM940, we have precision-matched components to suit your build.

Frequently Asked Questions
Q: What is the difference between 416 stainless steel and brass knife screws?
A: 416 stainless steel knife screws offer superior corrosion resistance and strength, making them ideal for everyday-carry and outdoor knives that are exposed to moisture. Brass knife screws and hardware, on the other hand, provide excellent machinability, a smooth bearing surface, and a classic aesthetic — they are a popular choice for traditional or decorative knife handle builds where corrosion exposure is minimal.
Q: What size knife handle screws do I need for my folding knife?
A: The most common screw sizes for DIY folding knife handle hardware are M3.5 and M4. M3.5 T8 Torx screws are widely used in production folding knives, while M4 bolts suit heavier-duty custom builds. Always measure the existing screw diameter and thread pitch before ordering, or consult your knife's specifications. Our product listings include detailed size information to help you find the perfect match.
Q: Are thrust bearings worth using in a folding knife build?
A: Yes — miniature thrust bearings are one of the best upgrades you can make to a folding knife. Replacing plain washers with steel ball thrust bearings dramatically reduces pivot friction, resulting in a faster, smoother one-hand opening action. They are especially valued in higher-end custom and production folders. Our F4-7 and F5-12 steel ball bearing sets are sized specifically for common folding knife pivot designs.
Q: Can I use these knife screws for Microtech knives?
A: Yes! We stock CNC-machined 416 stainless steel screws specifically designed as replacement and upgrade hardware for Microtech Ultratech, Venomtech, and Scarab knives. These precision screws ensure a proper fit and maintain the performance integrity of your Microtech blade.
