The VALUE COLLECTION 243507 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 5/16-18 x 1-1/4 inches overall length, it features an 82-degree flat head and a 3/8-inch hex socket drive. Constructed from 18-8 stainless steel, this screw resists corrosion in wet, marine, and chemically exposed environments. The Unified National Coarse (UNC) thread form provides reliable thread engagement in standard tapped holes. Installers working in HVAC, plumbing, electrical, and general mechanical assemblies will find this fastener suitable where a low-profile head is required.
This flat socket cap screw is used in residential and commercial mechanical assemblies where a recessed drive and flush seating are needed. Typical applications include panel mounting, equipment enclosures, pump housings, and structural hardware where the head must sit below or level with the mating surface. The 5/16-18 UNC thread makes it compatible with standard tapped holes and threaded inserts of the same size. It is appropriate for indoor and outdoor installations where stainless steel corrosion resistance is a requirement. Sold individually, with a minimum order quantity of 100 pieces.
Designed as a standard 5/16-18 UNC flat socket cap screw suitable for use in any application requiring an 82-degree countersunk hex socket fastener in 18-8 stainless steel.
Install using a 3/16-inch hex key or compatible hex bit driver. Ensure the mating hole is properly countersunk to 82 degrees for full head seating. Power down or de-energize any equipment before fastener installation in electrical or mechanical enclosures. Follow applicable torque guidelines for 5/16-18 stainless fasteners as specified in relevant industry or equipment service documentation.
