The VALUE COLLECTION R40691248 is a hex socket cap screw designed for fastening applications that require a recessed drive and a strong, corrosion-resistant material. Threaded to a 5/16-24 UNF specification, this fastener features a 3-inch length under the head and accepts a 1/4-inch hex drive. Constructed from 18-8 stainless steel, it delivers reliable resistance to rust and oxidation in wet, chemical-exposure, or outdoor environments. This screw is well-suited for mechanical assemblies, equipment fabrication, and maintenance work where a flush or below-surface head profile is required.
This fastener is commonly used in light industrial, commercial, and trade service applications. The 5/16-24 UNF thread pitch provides fine-thread engagement, which is preferred in applications requiring greater tensile strength or finer adjustment than a coarse-thread fastener allows. It is typically installed by HVAC technicians, plumbers, electricians, millwrights, and general maintenance personnel working on metal assemblies, brackets, panels, and mechanical equipment housings.
Designed as an OEM-style replacement or standard-use hex socket cap screw for any application requiring a 5/16-24 UNF thread, 3-inch length under head, and 1/4-inch hex drive in stainless steel.
Install using a calibrated hex key or socket driver sized for a 1/4-inch drive to avoid cam-out and fastener damage. De-energize or shut off any associated equipment before servicing assemblies that include this fastener. Apply a thread lubricant or anti-seize compound appropriate for stainless steel to prevent galling during installation. Follow applicable torque recommendations from the equipment manufacturer or applicable mechanical codes for the assembly being serviced.
