Value Collection 837035PR Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 837035PR is a 4-40 UNC hex socket cap screw designed for precision fastening in light-duty mechanical and electrical assemblies. This fully threaded fastener measures 3/8 inches in length under the head and accepts a 3/32-inch hex drive. Manufactured from alloy steel with a zinc-plated finish, it provides corrosion resistance suitable for indoor and general-purpose applications. The zinc coating conforms to ASTM B695. This screw is a standard choice for technicians and assemblers working in tight spaces where a hex key is the only practical tool option.

This fastener is suited for use in light mechanical assemblies, electronics enclosures, instrumentation panels, and small equipment frames where a 4-40 UNC thread pattern is specified. The compact 3/32-inch hex drive allows installation in confined areas. It is commonly specified by HVAC, electrical, and electronics assembly technicians when securing lightweight brackets, panels, or components that require a clean, low-profile cap-screw head.

Key Features

• 4-40 UNC thread for use in standard light-duty threaded applications
• 3/8-inch length under head — fully threaded for maximum thread engagement
• 3/32-inch hex socket drive for use with standard hex keys or Allen wrenches
• Alloy steel construction for strength appropriate to the fastener size
• Zinc-plated finish per ASTM B695 for corrosion resistance in general-purpose environments

Compatibility

Designed as a standard 4-40 UNC replacement or stock fastener for any assembly specifying a fully threaded hex socket cap screw in this thread size and length.

Installation Notes

Install using a 3/32-inch hex key or Allen wrench. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not overtighten — 4-40 fasteners have limited torque capacity relative to larger screw sizes. Minimum order quantity is 100 pieces per order.
