Value Collection -36826-1 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION -36826-1 is a 5/16-18 x 1-3/4 inch flat socket cap screw machined from alloy steel with a black oxide finish. It features an 82-degree flat head profile driven by a 3/16 inch hex socket and is fully threaded along its entire length. The black oxide finish provides a measure of corrosion resistance and reduces light reflection in service environments. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards, making it a reliable choice for precision mechanical assemblies where a flush or countersunk seating surface is required. Machinists, millwrights, and maintenance technicians are the primary installers.

This flat socket cap screw is suited for applications in machinery, fixtures, tooling plates, and industrial equipment where a low-profile, flush-mount fastener is needed. The UNC thread form is compatible with standard inch-system tapped holes. The alloy steel construction handles higher tensile and shear loads compared to standard steel grades, making it appropriate for load-bearing joints in mechanical and structural assemblies. Minimum order quantity is 25 pieces.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 3/16 inch hex socket drive for precise torque application
• Fully threaded for maximum thread engagement across the full grip length
• Alloy steel construction for elevated tensile strength
• Black oxide finish for mild corrosion resistance and reduced glare
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard inch-system UNC tapped holes accepting a 5/16-18 thread, compatible with countersunk or flat-bottom counterbored seats machined to accommodate an 82-degree flat head profile.

Installation Notes

Installation should be performed using a properly sized 3/16 inch hex key or socket bit to avoid rounding the drive recess. Ensure the mating tapped hole is clean and free of debris before installation. De-energize or lock out any equipment before servicing fasteners in live machinery per applicable safety standards. Do not exceed the recommended seating torque for the alloy steel grade being used as specified by the equipment manufacturer or applicable standards.
