Value Collection R40691126 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION R40691126 is a hex socket cap screw designed for applications requiring a compact drive interface and reliable fastener strength. Threaded to a 5/16-24 UNF specification with a 1-1/4 inch length under the head, this fastener accepts a 1/4 inch hex drive key for installation. Manufactured from 18-8 stainless steel, it provides corrosion resistance suitable for use in humid, wet, or chemically exposed environments. This screw is installed using a hex key or Allen driver and is commonly specified in mechanical assemblies, equipment fabrication, and general industrial maintenance work where a flush or low-profile head is required.

This fastener is appropriate for use in light to medium-duty mechanical assemblies across residential and commercial applications. The fine UNF thread pitch makes it well suited for applications where vibration resistance or precise torque control is important. Trades including HVAC technicians, plumbers, pipefitters, electricians, and general maintenance mechanics routinely use socket cap screws of this type when fastening panels, brackets, equipment covers, and component housings. The stainless steel construction makes it a common choice in pool equipment, marine environments, and other corrosive service conditions.

Key Features

• 5/16-24 UNF fine thread for improved vibration resistance and precise engagement
• 1-1/4 inch length under head fits a wide range of standard assembly stack-ups
• 1/4 inch hex drive accepts standard hex keys and Allen drivers
• 18-8 stainless steel construction offers strong corrosion resistance
• Low-profile socket cap head design suits recessed and tight-clearance installations

Compatibility

Designed as a standard UNF hex socket cap screw for use in any application requiring a 5/16-24 threaded fastener with a 1/4 inch hex drive and 1-1/4 inch length under head.

Installation Notes

Installation requires a properly sized 1/4 inch hex key or Allen driver. Ensure the mating threaded hole or nut matches the 5/16-24 UNF specification before driving. De-energize or shut down any equipment before accessing fastened assemblies. Stainless steel fasteners are susceptible to galling during installation — use anti-seize compound on threads when fastening stainless to stainless to prevent thread damage.
