Value Collection 211295P Flat Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 211295P is a flat socket cap screw designed for countersunk fastening applications requiring a flush or recessed head profile. Sized at 1/2-13 thread pitch and 1-1/2 inches overall length, it is fully threaded along its entire shank. The 82-degree flat head seats into standard countersunk holes and is driven by a 5/16-inch hex socket. Constructed from alloy steel with a black oxide finish, it offers improved corrosion resistance and reduced light reflection. This screw is installed by machinists, maintenance technicians, and fabricators working in general industrial, structural, and mechanical assembly environments.

This fastener is suited for applications where a low-profile or flush head is required and a standard hex socket driver is used. Fully threaded construction makes it effective in through-hole and short blind-hole applications. The UNC thread form and inch-system dimensions make it compatible with standard imperial tapped holes. It is commonly used in machine frames, fixtures, tooling plates, and equipment housings. Manufactured to ASME/ANSI B18.3 and ASTM F835 standards, it meets established dimensional and mechanical requirements for socket cap screws in industrial service.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 5/16-inch hex socket drive for standard Allen key or bit driver
• Fully threaded shank along entire 1-1/2-inch length
• Alloy steel construction for high tensile strength in demanding applications
• Black oxide finish for mild corrosion resistance and reduced glare
• Conforms to ASME/ANSI B18.3 and ASTM F835 dimensional and performance standards

Compatibility

Designed for use in standard UNC-tapped 1/2-13 through-holes requiring a countersunk flat-head socket fastener in inch-system assemblies.

Installation Notes

Install using a properly sized 5/16-inch hex key or socket bit driver to avoid rounding the drive recess. Ensure the mating hole is correctly countersunk to 82 degrees for full head seating. Apply appropriate thread lubricant or thread-locking compound as required by the application. Follow applicable torque specifications from engineering drawings or fastener manufacturer tables for alloy steel UNC fasteners of this diameter.
