The VALUE COLLECTION 88546999 is a 1/2-13 UNC hex socket cap screw designed for general industrial and mechanical fastening applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid tensile strength with moderate corrosion resistance in dry and mildly humid environments. The screw measures 1-3/4 inches in length under head and is fully threaded, providing consistent clamping force along the entire shank. Drive engagement is a 3/8-inch hex socket. This package contains 3 screws per unit, making it suitable for small-batch procurement or service-call quantities.
This socket cap screw is used across a wide range of trade and industrial applications including equipment mounting, machinery assembly, HVAC component brackets, electrical enclosure hardware, and structural fastening where a low-profile, high-strength threaded fastener is required. The 1/2-13 UNC thread is a coarse-thread standard widely used in steel and cast-iron assemblies. The black oxide finish keeps the fastener compact in appearance and reduces light reflection in panel and enclosure environments. Suitable for installation by HVAC technicians, electricians, millwrights, and general mechanical contractors.
Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use in any application requiring a fully threaded alloy steel fastener with a 3/8-inch hex drive and 1-3/4-inch length under head.
Install using a 3/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, free of debris, and correctly tapped to 1/2-13 UNC before installation. De-energize or shut down equipment before accessing any panels or enclosures for fastener service. Do not exceed the torque rating of the mating material, particularly when threading into aluminum or softer alloys.
