Value Collection 36840 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 36840 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 7/32-inch hex socket and is manufactured from alloy steel with a black oxide finish for corrosion resistance in moderate environments. The 3/8-16 UNC thread and 2-1/2-inch overall length make it suitable for medium-load structural and mechanical assemblies. The partial threading allows engagement with thicker workpieces while maintaining clamping force. Installers in mechanical, industrial, and trade-service applications use this screw where a low-profile head is required and access is available for a hex key or Allen driver.

This screw is used in general mechanical assemblies, fixtures, machine frames, and equipment enclosures where a countersunk fastener is needed to maintain a flush surface. Its UNC thread form is compatible with standard tapped holes and threaded inserts sized for 3/8-16. The black oxide finish suits interior and low-exposure applications. Minimum order quantity is 25 pieces per order, sold as a package quantity of 1.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 7/32-inch hex socket drive for use with standard Allen or hex keys
• Alloy steel construction for strength in medium-load fastening applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank allows use in thicker material assemblies
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC replacement or service fastener for any 3/8-16 countersunk hex socket application conforming to ASME/ANSI B18.3 flat socket cap screw dimensions.

Installation Notes

Installation is performed with a 7/32-inch hex key or Allen driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating. Torque to the fastener specification appropriate for the alloy steel grade and joint material. Always inspect threads and the countersunk seat for debris or damage before fastening.
