Value Collection 721024PR Flat Socket Cap Screw 3-48

Product Description

The VALUE COLLECTION 721024PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk seating surface is required. This fastener features an 82-degree flat head with a 1/16-inch hex socket drive and is fully threaded along its 3/4-inch overall length. The alloy steel construction delivers high tensile strength, and the black oxide finish provides moderate corrosion resistance and reduced light reflection in finished assemblies. Thread size is 3-48 UNC. Machinists, maintenance technicians, and assembly professionals install this type of fastener where a low-profile head is necessary and socket-drive torque is preferred over slotted or Phillips drive.

This screw is suited for light-duty mechanical assemblies, precision instrument panels, and machine components where a countersunk fastener is specified. The UNC thread standard and ASME/ANSI B18.3 and ASTM F835 compliance make it appropriate for applications requiring conformance to recognized dimensional and performance standards. The black oxide finish is commonly used in tooling, fixtures, and equipment where a non-reflective, functional surface is needed. This item is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head seats flush in countersunk holes for a low-profile assembly
• 1/16-inch hex socket drive for precise torque application in tight spaces
• Fully threaded 3/4-inch length maximizes thread engagement across the full shank
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers moderate corrosion resistance and a non-reflective appearance
• Conforms to ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style and general-use replacement or supplemental fastener for assemblies requiring a 3-48 UNC fully threaded flat socket cap screw with an 82-degree head angle.

Installation Notes

Installation requires a 1/16-inch hex key or socket driver. Ensure the mating hole is properly countersunk to 82 degrees before driving the fastener to avoid head distortion or improper seating. De-energize and lock out any powered equipment before performing fastener replacement or assembly work. Follow applicable torque guidelines for 3-48 alloy steel fasteners as specified in the relevant assembly or equipment service documentation.
