Value Collection R57001134 Hex Cap Screw 5/16-24 3in 18-8 Ss

Product Description

The VALUE COLLECTION R57001134 is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional precision. Manufactured from 18-8 stainless steel with a bright uncoated finish, this fastener measures 5/16-24 in thread size with a 3-inch length under head. The UNF thread form provides fine thread engagement for applications where vibration resistance or closer tolerance fits are required. Electricians, plumbers, HVAC technicians, and general trade professionals use hex head cap screws like this one when assembling or securing equipment panels, brackets, and mechanical supports in both interior and exposed environments.

This fastener is suited for residential and light commercial trade installations where stainless steel is specified to resist moisture, mild chemicals, or outdoor exposure. The fully threaded shank allows maximum thread engagement across the full 3-inch length, making it appropriate for through-bolting thin stock or securing threaded inserts. The 5/16-24 UNF designation is commonly encountered in HVAC equipment mounting, electrical panel hardware, and plumbing fixture assemblies where fine-thread fasteners are called out by equipment manufacturers.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor service conditions
• Fully threaded shank along the full 3-inch length under head for maximum engagement
• 5/16-24 UNF fine thread for vibration-resistant clamping and close-tolerance fits
• Bright uncoated finish — no plating to chip, flake, or compromise thread fit
• Inch measurement system with length measured under the head per standard fastener convention

Compatibility

Designed as a standard 5/16-24 UNF hex head cap screw for use in any application calling for a fully threaded stainless steel fastener in that thread size and 3-inch length.

Installation Notes

Install using the appropriately sized hex wrench or socket driver; a 1/2-inch wrench is the standard drive size for 5/16-inch hex cap screws. De-energize electrical systems and shut off fluid supply lines before fastening or removing hardware on live equipment. Apply anti-seize compound if the mating material is also stainless steel to prevent galling during tightening. Follow applicable codes and equipment manufacturer torque guidance when securing structural or pressure-bearing assemblies.
