Value Collection 36824 Flat Socket Cap Screw 5/16-18 X 1 in

Product Description

The VALUE COLLECTION 36824 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 3/16-inch hex socket, making it compatible with standard hex key sets. The fastener is fully threaded with a 5/16-18 UNC thread specification and measures 1 inch in overall length. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and a low-reflectivity appearance. This screw meets ASME/ANSI B18.3 and ASTM F835 standards. It is installed by electricians, HVAC technicians, plumbers, and mechanical contractors wherever a flush-seated socket cap fastener is required.

This screw is suited for use in mechanical assemblies, equipment panels, fixtures, and structural components where the fastener head must sit flush with or below the mating surface. The 5/16-18 UNC thread pattern is a common inch-series coarse thread, widely used in general industrial and trade applications. The black oxide alloy steel construction makes it appropriate for interior or lightly protected environments where a clean, finished appearance is preferred over raw steel.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 3/16-inch hex socket drive compatible with standard hex keys
• Fully threaded 5/16-18 UNC coarse thread, 1 inch overall length
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish reduces reflectivity and provides light corrosion resistance

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any assembly or fixture requiring a 5/16-18 UNC fully threaded fastener with an 82-degree countersunk head.

Installation Notes

Install using a 3/16-inch hex key or socket driver. Ensure the mating surface is properly countersunk to 82 degrees before seating the fastener. Do not exceed the rated drive engagement by using an undersized or worn hex key, as this may strip the socket. Black oxide finish is not a heavy-duty corrosion barrier; apply additional protective coating if the fastener will be exposed to moisture or outdoor conditions.
