Value Collection 211209P Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 211209P is a flat socket cap screw designed for countersunk fastening applications in mechanical assemblies, fixtures, and structural joints. Sized at 3/8-16 thread by 3/4 inches overall length and fully threaded, it seats flush or below the surface of the mating material. The 82-degree flat head and 7/32-inch hex socket drive allow installation with a standard hex key or socket driver. Manufactured from alloy steel with a black oxide finish, this screw provides solid mechanical strength and moderate corrosion resistance in dry or lightly oiled environments. Installed by machinists, maintenance technicians, and mechanical contractors.

This fastener is suited for use in machine tools, jigs, fixtures, structural assemblies, and general manufacturing applications where a flush or recessed head profile is required. The UNC thread form and ASME/ANSI B18.3 and ASTM F835 standards make it a recognized specification part for industrial and OEM applications. Full threading along the 3/4-inch shank length maximizes thread engagement for shorter grip lengths. Minimum order quantity is 100 pieces per order.

Key Features

• 82-degree flat head seats flush or below surface for a clean, snag-free profile
• 7/32-inch hex socket drive for precise torque application with a standard hex key
• 3/8-16 UNC thread, fully threaded over the 3/4-inch overall length
• Alloy steel construction for high tensile strength in demanding fastening applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in countersunk through-holes tapped or clearance-drilled to 3/8-16 UNC specification in metal, composite, or plastic assemblies requiring a flush-mount fastener profile.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 7/32-inch hex key or hex socket driver. Ensure the receiving hole is properly countersunk to 82 degrees to allow full head seating. De-energize and lock out any equipment before servicing assemblies that include these fasteners. Do not exceed the rated torque for 3/8-16 alloy steel fasteners as specified by the applicable engineering standard for the joint being assembled.
