Sold in packs of 25, these stainless steel 4-40 button head Torx (T-8) precision screws are built for makers who expect dependable strength, accurate fit and professional-quality hardware on custom work. They come in several thread lengths and are ideal for custom knives, firearm accessories, holsters, sheaths, EDC gear and other precision assembly jobs.
The high-quality stainless steel gives them exceptional durability and corrosion resistance while keeping the tight tolerances fine craftsmanship requires. Certain models use DFARS-compliant 302HQ stainless steel and are proudly made in the USA. If you want titanium, those versions are sold separately in the 4-40 Screws - Titanium group.
Each head design, button, flat and socket, has its own listing. Torx drive models transfer torque strongly and lower the risk of stripping, while Phillips drive options remain an excellent pick for traditional assemblies. Whether the job needs a low-profile button head, a flat head that mounts flush or a socket head with a secure recessed fit, this collection has the precision hardware for professional results.
Made for knife makers, gunsmiths, holster builders and craftsmen who refuse to compromise on quality, these hard-to-find 4-40 precision screws bring the performance, appearance and reliability your projects deserve. Choose your thread length above.
