Value Collection 92118 Hex Socket Cap Screw 4-40 Unc 25 Pack

Product Description

The VALUE COLLECTION 92118 is a 4-40 UNC hex socket cap screw designed for precise, low-profile fastening in mechanical assemblies, electrical enclosures, and instrumentation applications. Machined from 18-8 stainless steel, it delivers corrosion resistance suitable for both indoor and outdoor environments. The 3/32 inch hex drive accepts a standard Allen key or hex bit driver. The 1-1/4 inch length under head provides adequate thread engagement for thin-panel and light-structural applications. This package contains 25 screws, making it practical for bench stock and small assembly runs. Electricians, HVAC technicians, and mechanical assemblers commonly use 4-40 socket cap screws for panel mounting and equipment enclosure work.

This screw is suited for residential and light commercial applications where a compact, recessed drive head is required. Common install scenarios include securing control boards, terminal blocks, junction box covers, and instrumentation brackets. The 4-40 UNC thread form is a standard unified coarse thread widely used in precision mechanical and electrical hardware. The 18-8 stainless steel construction makes this fastener appropriate for environments with moisture exposure or where corrosion resistance is a maintenance priority.

Installation Notes

Install using a 3/32 inch hex key or hex bit driver rated for the socket cap screw torque range appropriate to 4-40 stainless steel fasteners. Do not use power tools without torque limiting control, as 4-40 screws can be damaged by over-torquing. Ensure mating threads are clean and properly tapped before installation. Electricians and mechanical technicians installing screws in live panels must de-energize equipment before beginning fastener work per NFPA 70E safe work practices.
