Value Collection 88546676 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88546676 is a hex socket cap screw designed for fastening applications requiring a recessed drive and a clean, low-profile head. Sized at 1/4-20 UNC thread and 1 inch in length under the head, this fastener is partially threaded and driven with a 3/16-inch hex key. The alloy steel construction provides high tensile strength, and the black oxide coating offers mild corrosion resistance and reduced light reflection. This type of fastener is used across mechanical, structural, and equipment assembly work by machinists, millwrights, and maintenance technicians.

This screw is suited for light industrial, commercial, and mechanical assembly applications where a socket drive is preferred over an external hex or slotted head. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in North American equipment, making this screw a frequent replacement or assembly fastener in machinery frames, brackets, jigs, fixtures, and enclosures. The partial threading is typical for clamping applications where the unthreaded shank provides a bearing surface.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1 inch length under head suits moderate-depth fastening applications
• 3/16-inch hex socket drive for use with standard hex keys or Allen drivers
• Partial threading provides an unthreaded shank for accurate alignment and clamping
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and a non-reflective surface

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring this thread size and drive type with a 1-inch length under head.

Installation Notes

Installation is performed with a 3/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not over-torque alloy socket cap screws; follow equipment manufacturer torque specifications for the fastener grade in use. Always de-energize or lock out equipment before performing any fastener work on live machinery per applicable safety standards.
