GrovTec US Inc GTHM59 steel machine screws are the unsung backbone of reliable firearm accessory attachment. These 0.25" fasteners are engineered for the critical job of securing sling swivel studs, bipod mounts, and other hardware to your rifle or shotgun—the kind of hardware failure you never want to discover downrange. Built to exacting standards by a manufacturer with deep roots in the gunsmithing supply world, these screws deliver the holding power and corrosion resistance that serious shooters and gunsmiths depend on.
Whether you're building a rifle from the ground up, replacing worn hardware on a trusted hunting rifle, or maintaining a collection of tactical carbines, having quality fasteners on hand matters more than most shooters realize. A stripped screw or a fastener that won't hold zero can turn a good shooting day into a frustrating one. The bulk pack format makes sense for armorers, gunsmiths, and dedicated shooters who maintain multiple firearms and want consistency across their fleet.
Made in the U.S.A., these screws reflect GrovTec's reputation for manufacturing products that outlast and outperform the typical import alternative. Steel construction provides the strength and durability needed for the repeated stress of shooting and field use. Keep a supply on hand—these are the kind of details that separate a well-maintained rifle from one waiting for a problem to surface.
