Value Collection R40664432 Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION R40664432 is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Threaded to 4-40 UNC, it features a 3/32 inch internal hex drive and measures 3/4 inch in length under the head. Manufactured from 18-8 stainless steel, the fastener offers solid corrosion resistance suitable for general-purpose mechanical assemblies. Licensed tradespeople and maintenance technicians working in HVAC, electrical enclosures, plumbing fixtures, and light mechanical equipment rely on socket cap screws of this type for clean, recessed fastening in tight-clearance applications.

This fastener is appropriate for light-duty threaded assemblies where a standard hex socket drive and fine 4-40 UNC thread form are required. It is commonly used in electrical panel assemblies, instrument enclosures, control board mounting, small appliance frames, and general sheet-metal fabrication. The 18-8 stainless steel construction makes it suitable for both indoor and moderately humid environments. Sold individually but available in multiples of 100 units to meet project quantity requirements.

Key Features

• 4-40 UNC thread form provides fine pitch engagement in precision tapped holes
• 3/32 inch hex socket drive accommodates standard Allen keys and hex bit drivers
• 3/4 inch length under head suits medium-depth fastening in stacked assemblies
• 18-8 stainless steel construction resists corrosion in general-purpose environments
• Socket cap head profile allows installation in recessed or counter-bored applications

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application requiring an 18-8 stainless steel fastener with a 3/32 inch drive and 3/4 inch under-head length.

Installation Notes

Install using a calibrated 3/32 inch hex key or Allen bit driver to avoid stripping the socket. De-energize and lock out any electrical or mechanical equipment before fastener installation or removal, per OSHA lockout/tagout procedures. Do not apply excessive torque to small-diameter screws in this thread class, as 4-40 fasteners are susceptible to thread shear in soft base materials.
