Value Collection 211217P Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 211217P is a flat socket cap screw designed for flush-mount fastening applications in structural and mechanical assemblies. It features a 3/8-16 UNC thread with a 1-3/4 inch overall length and is fully threaded along its entire length. The 82-degree flat head seats flush with or below the mating surface, and the 7/32 inch hex socket drive accepts a standard hex key for installation. Constructed from alloy steel with a black oxide finish, this fastener meets ASME/ANSI B18.3 and ASTM F835 dimensional and mechanical standards. It is installed by machinists, millwrights, and maintenance technicians across a wide range of industrial and commercial applications.

This screw is suited for use in machinery, fixtures, tooling, and structural steel assemblies where a flush or countersunk fastener profile is required. The black oxide finish provides moderate corrosion resistance and reduces light reflection, making it appropriate for both functional and low-visibility installations. Fully threaded construction allows for consistent clamping force even in shorter engagement depths, which is useful in thin plate or close-tolerance applications.

Key Features

• 82-degree flat head seats flush with the mating surface for a low-profile installation
• Fully threaded 3/8-16 UNC shank for consistent grip across the entire fastener length
• 7/32 inch hex socket drive compatible with standard hex keys and T-handle drivers
• Alloy steel construction meets ASTM F835 mechanical property requirements
• Black oxide finish provides moderate corrosion resistance and a non-reflective appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard-dimension replacement or new-install flat socket cap screw for applications requiring a 3/8-16 UNC thread, 1-3/4 inch overall length, and an 82-degree countersunk flat head per ASME/ANSI B18.3.

Installation Notes

Installation is performed using a 7/32 inch hex key or compatible socket driver. Countersink the mating hole to 82 degrees at the appropriate diameter before installation to achieve proper head seating. Ensure the workpiece material and thread engagement depth are appropriate for the torque requirements of the application. Follow applicable fastener standards and torque guidelines specified in the engineering documentation for the assembly.
