Value Collection R40631429 Hex Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION R40631429 is a hex socket cap screw designed for precision fastening in tight-clearance applications. It features a 1-72 UNF thread, a 1/16-inch hex drive, and a 1/4-inch length under head. Constructed from 18-8 stainless steel, this screw resists corrosion and maintains strength across a wide range of service environments. The fine unified thread pitch delivers secure clamping in thin or soft materials where standard coarse threads would strip. Trade professionals reach for this fastener when working with instrument panels, electrical enclosures, small mechanical assemblies, and other applications requiring a compact, corrosion-resistant cap screw.

This screw is suited for light-duty mechanical and electrical assembly work in residential, commercial, and industrial settings. The 1-72 UNF thread is a fine-pitch standard commonly found in instrumentation, control panels, and precision sheet metal assemblies. The hex socket drive allows installation with a 1/16-inch hex key in recessed or low-clearance spaces where slotted or Phillips drivers are impractical. Electricians, HVAC controls technicians, and general maintenance professionals will encounter this fastener size when servicing panel-mounted components and control hardware.

Key Features

• 1-72 UNF fine thread for secure engagement in thin or soft base materials
• 1/16-inch hex socket drive for use in tight or recessed locations
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• 1/4-inch length under head suits shallow fastening applications in panels and enclosures
• Cap screw head style delivers a clean, low-profile seating surface

Compatibility

Designed as a standard 1-72 UNF hex socket cap screw for use in precision mechanical assemblies, instrumentation housings, electrical enclosures, and control panel applications requiring an 18-8 stainless steel fastener with a 1/16-inch hex drive.

Installation Notes

Installation requires a 1/16-inch hex key or hex bit driver. Confirm thread engagement before applying torque to avoid cross-threading in fine-pitch tapped holes. De-energize any electrical enclosure or control panel before performing fastener service work. Stainless fasteners can gall during installation — applying a small amount of anti-seize compound to the threads is common practice in stainless-to-stainless applications.
