Value Collection 721316BR Flat Socket Cap Screw 1-8x2 in

Product Description

The VALUE COLLECTION 721316BR is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies and structural connections. Machined from alloy steel with a black oxide finish, this screw offers solid corrosion resistance and a clean appearance in finished assemblies. It measures 1-8 thread size by 2 inches in overall length and is fully threaded, providing maximum thread engagement throughout the grip length. The 82-degree flat head seats flush with the mating surface when installed in a properly chamfered hole. Drive engagement is through a 5/8-inch hex socket, requiring a standard hex key or Allen driver. Licensed trades and industrial maintenance technicians are the primary installers of this fastener type.

This flat socket cap screw is suited for use in mechanical assemblies where a low-profile, countersunk fastener is required. Common applications include machine frames, fixtures, tooling plates, structural brackets, and enclosure panels where the fastener head must sit flush with or below the work surface. The fully threaded shank makes this screw appropriate for through-hole applications with a nut or for tapped-hole assemblies with sufficient thread depth. It conforms to ASME/ANSI B18.3 and ASTM F835 standards, making it acceptable for use in applications with defined fastener specifications.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 5/8-inch hex socket drive for positive torque transfer with standard hex keys
• Alloy steel construction for high tensile strength in demanding assemblies
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded shank maximizes thread engagement in tapped holes or with a nut
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC flat socket cap screw for use in inch-series tapped or through-hole applications requiring a 1-8 thread size and 2-inch overall length with an 82-degree countersunk head.

Installation Notes

Installation requires a properly sized countersunk hole bored to an 82-degree included angle to achieve correct head seating. Use a calibrated torque wrench with the appropriate 5/8-inch hex bit to tighten to the value specified by the assembly drawing or applicable fastener standard. Ensure the tapped hole or nut thread class is compatible with the UNC thread standard before installation. De-energize and lock out any equipment before replacing or installing fasteners in live machinery.
