Value Collection 721200PR Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 721200PR is a flat socket cap screw designed for countersunk fastening applications where a flush or recessed head profile is required. The screw features a hex socket drive measuring 7/32 inches and is manufactured from alloy steel with a black oxide finish for moderate corrosion resistance. It measures 3-1/2 inches in overall length with a 3/8-16 UNC thread and is partially threaded. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards. It is installed by machinists, millwrights, maintenance technicians, and general fabricators in both industrial and commercial settings.

This screw is suited for applications requiring a low-profile or flush-mount fastener in metal assemblies, jigs, fixtures, machine frames, and structural components. The black oxide finish provides a clean appearance and light surface protection, making it appropriate for indoor or controlled-environment use. The UNC thread form is compatible with standard inch-system tapped holes and nuts. Partial threading is typical for longer cap screws of this size and helps maintain clamping force across thicker material stacks.

Key Features

• Flat head profile allows flush or countersunk seating in mating material
• 7/32-inch hex socket drive accepts standard hex keys and allen wrenches
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers light corrosion resistance and reduced glare
• Partially threaded shank suits thicker material stack-ups and shear-loaded joints
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in 3/8-16 UNC tapped holes in metal assemblies, machine structures, and fabricated components.

Installation Notes

Installation requires a properly sized 7/32-inch hex key or allen driver. The mating hole should be drilled and countersunk to the appropriate flat-head angle before installation. Ensure the tapped hole depth and thread engagement meet design requirements for the load being applied. Always de-energize or lock out equipment before replacing fasteners on live machinery.
