Value Collection 211211P Flat Socket Cap Screw 3/8-16x1 in

Product Description

The VALUE COLLECTION 211211P is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 7/32-inch hex socket and is fully threaded along its 1-inch overall length with a 3/8-16 UNC thread. Manufactured from alloy steel with a black oxide finish, it delivers solid mechanical strength and moderate corrosion resistance in a compact, low-profile form. Machinists, millwrights, and maintenance technicians commonly use this fastener where a protruding head is not acceptable.

This screw is suited for use in machine assemblies, fixtures, tooling plates, and mechanical equipment where a countersunk socket fastener is required. The 3/8-16 UNC thread is a standard inch-series coarse thread, making it compatible with tapped holes or threaded inserts machined to that specification. The black oxide finish is typically used in industrial or indoor environments where light corrosion protection is needed without adding significant dimensional buildup. Minimum order quantity is 100 pieces per order.

Key Features

• 82-degree flat head sits flush with or below the mounting surface when countersunk properly
• 7/32-inch hex socket drive for precise torque application with standard hex keys
• Fully threaded 1-inch overall length on 3/8-16 UNC thread for maximum thread engagement
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers light corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension replacement or new-installation fastener for any application requiring a 3/8-16 UNC fully threaded flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a calibrated hex key or socket driver sized at 7/32 inch. The mating countersink should be machined to an 82-degree angle to achieve proper head seating. De-energize or lock out any equipment before installing or removing fasteners in powered assemblies. Do not exceed the rated torque for the fastener grade, and inspect threads for damage before installation.
