Value Collection R40692103 Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION R40692103 is a hex socket cap screw designed for applications requiring a recessed hex drive and secure clamping force. Threaded to 3/8-24 UNF — a fine-thread specification that resists loosening under vibration — the fastener measures 1-1/2 inches in length under the head. Drive engagement is handled by a 5/16 inch hex key. The body is machined from 18-8 stainless steel, offering corrosion resistance in moisture-exposed or chemically active environments. This fastener is installed by maintenance technicians, millwrights, and field service professionals across mechanical assembly, equipment mounting, and structural fastening tasks.

This screw suits residential and light commercial mechanical assemblies where fine-thread fastening and corrosion resistance are priorities. Typical applications include pump housings, HVAC equipment brackets, panel mounting, and general-purpose machinery fastening. The 3/8-24 UNF thread pitch is commonly specified in precision-fit applications and in assemblies that require frequent removal and reinstallation without thread wear. The 18-8 stainless alloy makes it appropriate for wet environments, coastal installations, and food-adjacent equipment service.

Key Features

• 3/8-24 UNF fine-thread for vibration resistance and precision fitment
• 1-1/2 inch length under head for standard-depth engagement in typical assemblies
• 5/16 inch hex socket drive for use with standard Allen keys or hex bits
• 18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments
• Socket cap head profile allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard 3/8-24 UNF hex socket cap screw for use in any mechanical assembly, fixture, or equipment application specifying that thread size and a 1-1/2 inch length under head in 18-8 stainless steel.

Installation Notes

Install with a 5/16 inch hex key or an appropriate hex bit and driver. De-energize, depressurize, or otherwise isolate the equipment before fastener service to prevent injury. Do not overtighten stainless steel fasteners, as galling can occur — apply an appropriate anti-seize compound when installing into stainless or aluminum threaded holes. Fastener selection and torque requirements should conform to the equipment manufacturer's specifications and applicable codes.
