Value Collection 837037PR Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 837037PR is a hex socket cap screw designed for precision fastening in light mechanical assemblies. Threaded 4-40 UNC with a 1/2 inch length under head, this screw is fully threaded from head to tip, providing maximum thread engagement for its size. The 3/32 inch hex drive socket accepts a standard hex key or Allen driver. Constructed from alloy steel with a zinc-plated finish per ASTM B695, it offers corrosion resistance suitable for general indoor mechanical and electrical panel applications. This fastener is sized for fine-pitch, small-diameter work common in instrument assembly, electronics enclosures, and light equipment fabrication.

This screw is used in applications requiring a compact, high-strength fastener at the 4-40 UNC thread standard. Typical install scenarios include securing small brackets, terminal boards, covers, and sub-assemblies in electronic equipment, HVAC controls, or light industrial machinery. The fully threaded shank allows use in thin material with minimal grip length. Sold as a single piece with a minimum order quantity of 100 units, this fastener is suited for shop stock, MRO replenishment, or production line use.

Key Features

• 4-40 UNC thread for fine-pitch, small-diameter fastening
• Fully threaded shank maximizes thread engagement in thin materials
• 3/32 inch hex socket drive for Allen key installation in tight spaces
• Alloy steel construction provides strength at small fastener sizes
• Zinc-plated finish meets ASTM B695 for corrosion resistance
• 1/2 inch length under head suits standard light-gauge panel and bracket work

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application requiring this thread form and drive type. Confirm thread size, length, and drive requirements against your assembly specifications before ordering.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver. Verify that the mating threaded hole or nut is tapped to 4-40 UNC specification before driving the fastener. Do not exceed appropriate seating torque for this screw size, as alloy steel small-diameter fasteners can be damaged by over-tightening. When used in electrical enclosures or control panels, follow applicable NEC guidelines for hardware installation near energized components.
