Description
These HILLMAN socket-head cap screws are precision fasteners designed for applications that need a clean, strong, low-profile connection. Made from steel alloy with a black oxide finish, the 1/4"-28 x 1/2" screws offer SAE fine threads and a compact socket head that accepts an Allen wrench for snug, reliable clamping. Ideal for light machinery assembly, electronics enclosures, furniture projects, automotive trim, and metalworking tasks, they provide corrosion-resistant appearance and a consistent fit where space is limited. The black finish reduces glare and blends into darker components while the fine threading helps achieve controlled torque and vibration resistance in threaded assemblies. Manufactured in TW, these screws suit both repair and new-build jobs where a durable, professional-looking fastening solution is required.
