Value Collection R57001047 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION R57001047 is a hex socket cap screw with a 5/16-24 UNF thread and a 2-1/4-inch length under the head. It is driven with a 1/4-inch hex key and manufactured from 18-8 stainless steel with a bright, uncoated finish. This fastener is a standard socket head cap screw designed for mechanical assemblies, equipment mounting, and structural connections where corrosion resistance and thread precision matter. Maintenance technicians, millwrights, and trade professionals use this type of fastener across a wide range of industrial and commercial applications.

This screw fits applications requiring a fine-thread UNF fastener in 5/16-inch diameter, including HVAC equipment panels, plumbing fixture brackets, electrical enclosures, and light structural assemblies. The 18-8 stainless steel construction makes it suitable for environments with moisture exposure or mild corrosive conditions. It is sold individually per package, with a minimum order quantity of 10 pieces.

Installation Notes

A 1/4-inch hex key or Allen-head socket is required for installation. De-energize and depressurize any equipment before fastener replacement or installation. Use a calibrated torque wrench when assembly specifications require controlled clamping force. Apply thread lubricant or anti-seize compound where stainless-to-stainless galling is a concern.
