Socket Screws – Fasteners for Precision Assembly & High-Torque Applications

Socket screws, also known as Allen screws or hex socket screws, are designed for high-strength, precision fastening in machinery, fabrication, & equipment assembly. With internal hex drives, they enable tight installation in confined spaces & deliver superior torque transfer. Available in cap head, button head, & countersunk varieties, our socket screws are ideal for mechanical repairs, tooling setups, & metalwork builds.

What’s in This Collection:
► Socket cap screws for strong mechanical joints
► Button head & countersunk options for low-profile assembly
► Metric & imperial sizes in alloy, stainless, & black oxide
► Precision-machined threads for accurate fit
► Bulk packs for manufacturing & repair workshops
