Value Collection R40694486 Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION R40694486 is a hex socket cap screw designed for fastening applications that require a clean, recessed drive profile and corrosion-resistant construction. Threaded to a 1/4-28 UNF specification, this fine-thread fastener features a 3/16 inch hex drive and a length under head of 7/8 inch. The body is machined from 18-8 stainless steel, providing solid resistance to rust and oxidation in wet, outdoor, or chemically active environments. This screw is a standard choice for mechanical assemblies, equipment panels, and structural connections where a socket drive is preferred for torque application in tight spaces.

This fastener suits a wide range of residential, commercial, and light industrial assembly tasks. Typical applications include HVAC equipment panels, plumbing fixture brackets, electrical enclosures, and general mechanical assembly. The fine 1/4-28 UNF thread pitch makes it well suited for thin-material joints or applications requiring precise clamping force. Installers across trades reach for 18-8 stainless socket cap screws when stainless fasteners are specified for corrosion-prone locations such as mechanical rooms, rooftop equipment, or coastal installations.

Key Features

• 1/4-28 UNF fine thread for precise engagement and higher thread-strip resistance compared to coarse thread
• 3/16 inch hex socket drive for use with standard hex keys or Allen-head bit drivers
• 7/8 inch length under head accommodates common panel and bracket thicknesses
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Recessed cap head profile sits flush with or below surface level in counterbored holes

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw suitable for use in mechanical assemblies, equipment enclosures, and structural fastening applications that accept this thread size and drive type.

Installation Notes

Install using a 3/16 inch hex key or matching socket bit driver. Ensure the mating thread is clean and free of debris before driving. De-energize any electrical equipment and shut off fluid systems before accessing fastened components during service. Follow applicable NEC or mechanical code requirements for fastener specifications in code-governed installations.
