Value Collection R40631440 Hex Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION R40631440 is a hex socket cap screw designed for precision fastening applications requiring a compact drive interface. This screw features a 1-72 UNF thread form, a 3/8 inch length under head, and a 1/16 inch hex drive socket. It is manufactured from 18-8 stainless steel, which provides corrosion resistance suitable for light industrial, instrumentation, and mechanical assembly environments. The fine 1-72 UNF thread pitch offers strong thread engagement in thin or soft materials. Installers in electrical, HVAC, and light mechanical trades use this fastener when secure, small-profile fastening is required in tight clearances.

This hex socket cap screw is suited for applications where a standard Phillips or slotted drive is not practical due to space constraints or torque requirements. The 1/16 inch hex drive accepts a standard hex key or Allen wrench. It is commonly used in control panel assembly, instrumentation mounting, small appliance repair, and precision mechanical assemblies found in residential and commercial equipment. The 18-8 stainless steel construction makes it appropriate for indoor environments with exposure to moisture or mild corrosives.

Key Features

• 1-72 UNF fine thread for strong engagement in thin materials
• 3/8 inch length under head for shallow fastening applications
• 1/16 inch hex socket drive accepts standard Allen keys
• 18-8 stainless steel construction resists corrosion
• Compact cap head profile suits tight clearance installations

Compatibility

Designed as a standard 1-72 UNF hex socket cap screw suitable for use in precision mechanical assemblies, instrumentation panels, and small-component fastening applications where this thread size and drive type are specified.

Installation Notes

Installation requires a 1/16 inch hex key or Allen wrench. Ensure the mating threaded hole or nut is clean and free of debris before driving the screw. Power down or de-energize any electrical or mechanical assembly before accessing fastener locations inside live panels. Do not overtighten stainless steel fasteners in stainless threaded inserts, as galling can occur; apply an appropriate anti-seize compound if required by the assembly specification.
