Value Collection 36827 Flat Socket Cap Screw 5/16-18x2 in

Product Description

The VALUE COLLECTION 36827 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Featuring an 82-degree flat head with a 3/16-inch hex socket drive, this screw seats flush with or below the surface of the mating material when installed in a properly countersunk hole. It is fully threaded along its 2-inch overall length using a 5/16-18 UNC thread form. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. This type of fastener is commonly installed by machinists, millwrights, and maintenance technicians in both production and field service environments.

This flat socket cap screw is suited for use in machinery, fixtures, jigs, and structural assemblies where a recessed or flush fastener is required. The hex socket drive accommodates standard hex keys and socket bit drivers, allowing installation in confined spaces where wrenching access is limited. The UNC thread form and adherence to ASME/ANSI B18.3 and ASTM F835 standards make this screw compatible with standard tapped holes across a wide range of industrial and mechanical applications.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 3/16-inch hex socket drive for use with Allen keys or hex bit drivers
• Fully threaded over the entire 2-inch length for maximum thread engagement
• Alloy steel construction provides high tensile strength
• Black oxide finish offers mild corrosion and oxidation resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard countersunk holes with a 5/16-18 UNC tapped thread. Suitable for machinery, fixtures, and assemblies requiring a flush-mount fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 3/16-inch hex key or hex socket bit. The mating hole should be countersunk to 82 degrees to achieve a proper flush seating of the head. Ensure the tapped hole meets the correct thread specification before driving the fastener to avoid cross-threading. Follow applicable torque guidelines for 5/16-18 alloy steel fasteners as specified in the relevant engineering standard for the assembly.
