Value Collection 88546684 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 88546684 is a partially threaded hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assembly applications. It features a 1/4-20 UNC thread size with a 1-1/4 inch length under head and a 3/16 inch hex drive socket. Constructed from alloy steel with a black oxide finish, this fastener offers good tensile strength and mild corrosion resistance in controlled environments. The black oxide coating reduces light reflection and provides a degree of surface protection. Each package contains 13 screws, making this suitable for both single-repair service calls and small-batch assembly work. Licensed trades and maintenance technicians working in HVAC, electrical, and mechanical systems will find this a standard cap screw for panel and bracket fastening.

This hex socket cap screw is suited for residential and light commercial applications where a recessed-drive fastener is required to keep a flush or low-profile surface. The hex socket drive allows use in confined spaces where a standard hex head wrench cannot turn freely. Partial threading provides clamping force between joined materials, making it appropriate for fastening metal brackets, access panels, equipment housings, and structural assemblies where thread engagement in a tapped hole is required. No specific OEM system compatibility was provided with this product.

Key Features

• 1/4-20 UNC thread form for wide compatibility with standard tapped holes
• 1-1/4 inch length under head for adequate thread engagement in typical bracket and panel stock
• 3/16 inch hex socket drive allows installation in tight or recessed spaces
• Partially threaded shank provides clamping grip across the joint interface
• Alloy steel construction delivers high tensile and shear strength
• Black oxide coating reduces surface corrosion in dry indoor environments

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application requiring a 1/4-20 tapped hole and a 3/16 inch hex drive tool. No specific OEM or system compatibility was listed for this part.

Installation Notes

Installation requires a 3/16 inch hex key or hex socket driver. Always confirm the receiving material has a properly tapped 1/4-20 UNC hole before driving the fastener to avoid cross-threading or stripping. De-energize and lock out any equipment before accessing panels or enclosures secured by these screws. Apply thread-locking compound where vibration is present, following the equipment manufacturer's service documentation.
