Value Collection 872035PR Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 872035PR is a 4-40 UNC hex socket cap screw designed for precision fastening in light-duty mechanical and electrical assemblies. It features a 3/8-inch length under head with full threading along the entire shank, accepting a 3/32-inch hex drive. Manufactured from alloy steel with a zinc-plated finish, this fastener provides corrosion resistance appropriate for indoor and light industrial service environments. It conforms to ASME B18.8 and ASTM A574 standards, making it a reliable choice for applications requiring dimensional consistency and verified material strength. Licensed trades, maintenance technicians, and assembly professionals working with small-format hardware will find this screw a standard fit for many control panel and equipment enclosure assemblies.

This screw is suited for residential and commercial applications where 4-40 UNC threaded fasteners are specified. Typical installations include electronic enclosures, HVAC control boards, small appliance frames, and precision instrument housings. The fully threaded shank maximizes thread engagement across the full grip length, which is particularly useful in thin-material assemblies or when using a threaded insert. Sold in minimum order quantities of 100, this screw is appropriate for stocking in service vehicle hardware kits or shop fastener bins.

Key Features

• 4-40 UNC thread size with full threading along the entire shank length
• 3/8-inch length under head for engagement in thin to medium material stacks
• 3/32-inch hex socket drive for use with standard Allen or hex key sets
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Zinc-plated finish provides corrosion resistance in indoor environments
• Conforms to ASME B18.8 dimensional standards for consistent fitment

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application specifying ASME B18.8 or ASTM A574 compliant fasteners of this thread size and length.

Installation Notes

Install using a calibrated 3/32-inch hex key or Allen driver to avoid rounding the socket drive. Confirm the mating thread is 4-40 UNC before installation to prevent cross-threading. Always follow applicable equipment manufacturer torque guidance and relevant codes such as NEC or ASME standards when fastening into electrical enclosures or pressure-bearing assemblies. Minimum order quantity is 100 pieces per purchase.
