Value Collection 721198PR Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 721198PR is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features an 82-degree flat head profile and a 7/32-inch hex socket drive, allowing installation with a standard hex key or Allen wrench. The fastener is machined from alloy steel and finished with black oxide for corrosion resistance and reduced light reflection. Measuring 3/8-16 thread size by 7/8 inches in overall length and fully threaded along its shank, it conforms to ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians commonly use these screws in precision assemblies where a low-profile head is required.

This screw is suited for use in industrial machinery, tooling fixtures, structural steel assemblies, and general mechanical fabrication where a countersunk fastening point is necessary. The UNC thread standard ensures broad compatibility with tapped holes in standard inch-system components. The black oxide finish makes it a common choice in applications where minimal surface reflectivity or a uniform dark appearance is preferred alongside functional corrosion protection. Sold individually per package with a minimum order quantity of 100 units.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 7/32-inch hex socket drive for use with standard Allen wrenches
• Fully threaded 3/8-16 UNC shank, 7/8 inches overall length
• Alloy steel construction for high tensile strength in demanding applications
• Black oxide finish provides mild corrosion resistance and low-reflectivity appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 3/8-16 UNC countersunk socket cap screw with an 82-degree flat head in inch-system assemblies.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or millwrights using a 7/32-inch hex key or Allen wrench. Ensure the receiving hole is drilled and countersunk to the correct 82-degree angle before installation. De-energize and lock out any machinery before fastener replacement or assembly work. Do not exceed the rated torque range for the fastener grade as defined by ASME standards for alloy steel socket cap screws.
