Value Collection MP72028 Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION MP72028 is a fully threaded hex socket cap screw designed for precision fastening in tight clearance applications. It features a 5-40 UNC thread size, a 1/4 inch length under the head, and a 3/32 inch hex drive. The screw is machined from alloy steel and finished with black oxide coating for corrosion resistance and a clean appearance. This fastener meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards. Sold in packs of 50, it suits machinists, maintenance technicians, and assembly professionals working on small mechanical and electronic components.

This screw is suited for applications requiring a small-diameter, fine-pitch fastener with a low-profile socket drive. Common uses include instrument assemblies, small motors, panel hardware, and precision mechanical equipment where controlled torque and flush or recessed installation are required. The black oxide finish reduces light reflection and provides mild corrosion protection in indoor or controlled environments. It installs using a standard 3/32 inch hex key or Allen driver.

Key Features

• 5-40 UNC fully threaded profile for fine-pitch, high-precision fastening
• 3/32 inch hex socket drive for use with standard Allen wrenches or hex keys
• 1/4 inch length under head for compact, low-profile installations
• Alloy steel construction for strength in small-diameter fastener applications
• Black oxide finish provides mild corrosion resistance and matte appearance
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards

Compatibility

Designed as a standard 5-40 UNC hex socket cap screw suitable for use in instrument panels, precision mechanical assemblies, and electronic equipment requiring small-diameter alloy steel fasteners.

Installation Notes

Install using a 3/32 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. De-energize any equipment fully before fastening components on live assemblies. Do not overtighten small-diameter alloy screws, as thread stripping is a common failure mode at this size.
