Holo-krome 78052 Hex Socket Cap Screw 1/4-20 Unc Stainless

Product Description

The HOLO-KROME 78052 is a hex socket cap screw designed for secure fastening in applications where a low-profile, high-strength connection is required. It features a 1/4-20 UNC thread size with a 3/8-inch length under the head and is fully threaded from end to tip. The 3/16-inch hex drive accepts a standard hex key or Allen wrench. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion and is suited for use in HVAC assemblies, plumbing equipment, electrical enclosures, and general mechanical installations. It meets ASME B18.3 and ASTM F837 fastener standards.

This cap screw is appropriate for light-duty to medium-duty mechanical assemblies in residential and commercial trade environments. Its compact 1/4-20 UNC thread profile and fully threaded shank make it a common choice for panel mounting, bracket fastening, and equipment assembly in HVAC units, pump housings, and electrical panels. The stainless steel construction makes it suitable for moist or corrosive environments where carbon steel fasteners would degrade over time. This item is sold individually but requires a minimum order quantity of 100 pieces.
