Value Collection 36856 Flat Socket Cap Screw 1/2-13 X 1-1/2 in

Product Description

The VALUE COLLECTION 36856 is a fully threaded flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. Built from alloy steel with a black oxide finish, this screw delivers solid mechanical strength alongside moderate corrosion resistance in a compact, low-profile head format. The 82-degree flat head seats cleanly into standard countersunk holes, and the 5/16-inch hex socket drive accepts a standard hex key for installation and removal. Thread size is 1/2-13 UNC, with an overall length of 1-1/2 inches. Meets ASME/ANSI B18.3 and ASTM F835 standards, making it suitable for general industrial and mechanical assembly work.

This fastener is appropriate for industrial machinery, structural assemblies, fixtures, and fabrication applications where a flush-mount fastener is required. The alloy steel construction handles higher tensile loads than standard carbon steel fasteners, and the black oxide finish reduces light reflection and provides light surface protection. Minimum order quantity is 10 pieces, with individual package quantity of 1. Suitable for use by millwrights, maintenance technicians, machinists, and fabricators working in manufacturing and industrial environments.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 5/16-inch hex socket drive for secure torque transfer with a standard hex key
• Fully threaded 1/2-13 UNC thread form along the entire 1-1/2-inch length
• Alloy steel construction for higher tensile and shear strength compared to low-carbon fasteners
• Black oxide finish reduces surface reflectivity and provides light corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or general-use fastener for applications requiring a 1/2-13 UNC fully threaded flat socket cap screw with an 82-degree countersunk head profile.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen-type driver. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Verify thread engagement depth meets the requirements of the joint design before final torque. Follow applicable ASME or industry torque guidelines for 1/2-13 alloy steel fasteners in the specific application material.
