Value Collection 011041P Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 011041P is a hex socket cap screw designed for precision fastening in mechanical assemblies, machine components, and equipment maintenance applications. It features a 4-40 UNC thread size and a 3/4-inch length under head with full threading along the entire shank. The drive is a 3/32-inch hex socket, requiring an Allen wrench or hex key for installation and removal. Constructed from alloy steel with a black oxide finish, this fastener offers solid mechanical strength and moderate corrosion resistance suited to controlled environments. Licensed tradespeople, machine technicians, and maintenance professionals commonly specify this screw type for close-tolerance work.

This fastener fits applications where a low-profile, high-strength socket head is required over a standard hex or Phillips drive. Common install scenarios include electronic enclosures, instrument panels, jigs, fixtures, light machinery, and HVAC equipment sub-assemblies. The 4-40 UNC thread is a standard unified coarse thread in the number 4 diameter range, widely used in light-duty mechanical and electromechanical assemblies. The black oxide coating reduces light reflection and provides a degree of lubricity during torquing. Sold individually, with a minimum order quantity of 100 pieces per order.

Key Features

• 4-40 UNC fully threaded shank for maximum thread engagement along the entire 3/4-inch length
• 3/32-inch hex socket drive for precise torque application with a standard Allen wrench
• Alloy steel construction provides higher tensile strength than standard carbon steel fasteners
• Black oxide finish offers mild corrosion resistance and reduces reflectivity in finished assemblies
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards
• Minimum order quantity of 100 pieces supports bulk maintenance and production use

Compatibility

Designed as an OEM-style replacement or standard-supply fastener for any assembly requiring a 4-40 UNC hex socket cap screw with a 3/4-inch length under head and a 3/32-inch hex drive.

Installation Notes

Installation is performed using a 3/32-inch hex key or Allen wrench; use a calibrated torque driver where the assembly specifies a torque value. Ensure mating threads are clean and free of debris before installation. Do not over-torque small-diameter fasteners such as 4-40 screws, as the thread engagement area is limited. Follow applicable assembly or equipment manufacturer guidelines for thread engagement depth and any required thread-locking compound.
