Value Collection R40684444 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R40684444 is a hex socket cap screw designed for secure, high-torque fastening in mechanical, plumbing, and general trade applications. It features a 1/4-20 UNC thread and measures 4 inches in length under the head, with a 3/16 inch internal hex drive. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet and outdoor environments. Installers use an Allen wrench or hex bit driver to seat the low-profile cap head flush or recessed into the mating surface. This screw is well suited for applications requiring a clean appearance and resistance to loosening under vibration.

This hex socket cap screw is used across residential and commercial trade work including equipment mounting, panel assembly, pump and motor brackets, and mechanical enclosures. The 1/4-20 UNC thread is a common inch-series thread and mates with standard tapped holes and hex nuts in that size. The 18-8 stainless steel construction makes it appropriate for damp locations, HVAC equipment enclosures, pool equipment installations, and other environments where carbon steel fasteners would corrode. Sold individually, with a minimum order quantity of 10 units.

Key Features

• 1/4-20 UNC thread — common inch-series thread for wide compatibility with standard tapped holes and hardware
• 4 inch length under head for deeper engagement in thicker assemblies
• 3/16 inch internal hex drive accepts standard Allen wrenches and hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet, damp, and outdoor service environments
• Low-profile socket cap head allows installation in recessed or countersunk applications

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use wherever that thread size and 4 inch under-head length are specified in mechanical assemblies and trade equipment installations.

Installation Notes

Installation requires a 3/16 inch hex key or Allen-style bit driver; confirm the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless threads to prevent galling. Torque to the specification listed in the equipment manufacturer's service documentation. Power down or depressurize any system before accessing fastener locations on live mechanical or electrical assemblies.
