Value Collection R63061022 Flat Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R63061022 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 3/8-inch hex socket drive and an 82-degree flat head geometry that seats flush with or below the material surface when installed in a properly countersunk hole. Manufactured from 18-8 stainless steel, this screw offers good corrosion resistance suitable for general industrial, mechanical, and light marine environments. The thread size is 5/8-11 UNC with an overall length of 3 inches. It is installed with a standard hex key or Allen wrench and is appropriate for use by machinists, millwrights, maintenance technicians, and mechanical contractors.

This screw is suited for fastening applications where the fastener head must sit flush with or recessed into the mating surface. Common installation scenarios include machine frames, fixture plates, enclosure panels, and structural assemblies requiring a clean, low-profile surface finish. The 5/8-11 UNC thread pattern is compatible with standard inch-series tapped holes of the same designation. The stainless steel construction makes it a practical choice in environments with exposure to moisture or mild chemicals where carbon steel fasteners would be prone to corrosion.

Key Features

• 82-degree flat head seats flush or below surface in countersunk holes
• 3/8-inch hex socket drive for use with standard hex keys or Allen wrenches
• 18-8 stainless steel construction for corrosion resistance
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes
• 3-inch overall length suits medium-depth fastening applications

Compatibility

Designed for use in standard inch-series 5/8-11 UNC tapped holes requiring a countersunk flat-head fastener.

Installation Notes

Install using the appropriate 3/8-inch hex key or Allen wrench; do not use an undersized driver as it may strip the socket. Ensure the mating hole is countersunk to the correct 82-degree angle before installation to achieve a proper flush seating. De-energize and lock out any equipment before servicing fasteners on powered machinery. Follow applicable facility or equipment manufacturer torque guidelines, as no torque specification is provided with this fastener.
