Value Collection R40694101 Hex Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R40694101 is a hex socket cap screw in 1/4-28 UNF thread with a 1-1/2 inch length under the head and a 3/16 inch hex drive. Manufactured from 18-8 stainless steel, this fastener offers reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The fine 1/4-28 UNF thread provides greater thread engagement per inch compared to coarse thread, making it well suited for precision assemblies and applications where vibration resistance matters. Licensed tradespeople and mechanical contractors install this type of fastener using a hex key or Allen driver in equipment panels, brackets, and structural assemblies.

This screw is appropriate for light industrial, HVAC, plumbing, and electrical panel applications where a compact fastener with a recessed drive head is required. The low-profile socket cap head allows installation in tight clearances where a hex bolt head would interfere. The 1/4-28 UNF thread specification makes it a common fit for machined metal components and threaded inserts used in residential and light commercial equipment assembly.

Key Features

• 1/4-28 UNF fine thread for higher thread engagement and vibration resistance
• 1-1/2 inch length under head for moderate fastening depth
• 3/16 inch hex socket drive for use with standard hex keys or Allen drivers
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Socket cap head profile allows installation in tight clearance applications

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw suitable for threaded metal components, machined inserts, and equipment assemblies requiring fine-thread stainless steel fasteners.

Installation Notes

Install using a calibrated hex key or Allen driver sized to 3/16 inch to avoid rounding the socket. De-energize and lock out any electrical equipment before accessing panels or enclosures where fasteners are being replaced. Follow applicable mechanical codes and equipment manufacturer torque guidance. Avoid mixing stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
