Value Collection 721048PR Flat Socket Cap Screw 5-40x1 in

Product Description

The VALUE COLLECTION 721048PR is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. Built from alloy steel with a black oxide finish, this screw provides moderate corrosion resistance and a clean appearance in finished assemblies. The 82-degree flat head seats into standard countersunk holes, while the hex socket drive allows precise torque application with a 5/64 inch hex key. At 1 inch in overall length and fully threaded, the 721048PR is suited for light-duty machine assembly and precision component work where head protrusion must be minimized.

This flat socket cap screw is used in machine assembly, fixture building, and equipment fabrication where a flush fastener is required. The 5-40 UNC thread size makes it appropriate for small-scale mechanical components, instrument housings, and light structural connections. Installers working in manufacturing, maintenance, and industrial trades will find this fastener compatible with standard countersunk hole patterns machined to ASME specifications. It is sold in a minimum order quantity of 100 pieces per order.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• Hex socket drive accepts a 5/64 inch hex key for controlled torque application
• Fully threaded 1 inch length for maximum thread engagement in thin and standard stock
• Alloy steel construction for strength in light-duty machine fastening applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC flat socket cap screw for use in countersunk hole applications machined to ASME/ANSI B18.3 specifications. Suitable for use wherever a 5-40 UNC fully threaded flat-head fastener is required.

Installation Notes

Installation requires a 5/64 inch hex key or matching hex bit driver. Ensure the mating countersink is machined to the correct 82-degree angle before seating the screw to avoid head damage or improper flush fit. Power down and de-energize any equipment before performing fastener service or disassembly. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
