Value Collection A997094 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION A997094 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 3/16-inch hex socket, making it compatible with standard Allen-style hex keys and socket drivers. Manufactured from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in indoor and light-duty environments. The 5/16-18 UNC thread and 3-1/2-inch overall length make it suitable for medium-duty assemblies where a low-profile head is needed. Threading is partial, meaning only a portion of the shank is threaded. Sold in packages of 25.

This fastener is commonly used in machine assembly, fixture building, jigs, brackets, and structural fabrication where a flush seating surface is required. The 82-degree flat head seats flush into a countersunk hole, eliminating protrusion that could interfere with mating surfaces or clearance envelopes. Typical installers include machinists, millwrights, and maintenance technicians working on industrial equipment, tooling, or structural steel components. The black oxide finish is suited for dry or lightly oiled indoor service conditions.

Key Features

• 82-degree flat head seats flush into standard countersunk holes
• 3/16-inch hex socket drive for Allen key or socket wrench installation
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank for secure clamping and alignment
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835, suitable for any assembly requiring a 5/16-18 UNC partially threaded flat head socket screw in a 3-1/2-inch overall length.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen socket driver; ensure the countersunk hole is machined to the correct 82-degree included angle to achieve full head seating. De-energize or lock out any equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque specification for the fastener grade and size as defined in ASME B18.3 torque tables. Inspect threads and countersink for debris or damage before assembly.
