Value Collection R63033841 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R63033841 is a 1/4-28 hex head cap screw manufactured from 18-8 stainless steel. It measures 3/4 inches under the head with a 7/16-inch hex drive and follows the Unified National Fine (UNF) thread standard. The 18-8 stainless steel construction provides solid corrosion resistance, making this fastener well-suited for applications where moisture or mild chemical exposure is a concern. Installers in HVAC, plumbing, electrical panel work, and general mechanical assembly use this screw type when a fine-thread, corrosion-resistant fastener is required.

This fastener is used across a wide range of light industrial and trade applications requiring a fine-thread pattern for increased holding strength or precision adjustment. The 1/4-28 UNF thread profile engages more threads per inch than coarse-thread equivalents, which is advantageous in thin-material connections and vibration-prone assemblies. Typical install scenarios include equipment panel mounting, bracket attachment, and mechanical assembly where stainless steel is specified to avoid galvanic incompatibility or rust staining.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and mildly corrosive environments
• 1/4-28 UNF thread provides finer pitch for stronger clamp load in thin materials
• 3/4-inch length under head suits shallow-through and blind-hole applications
• 7/16-inch hex drive accepts standard hex sockets and wrenches
• Inch-system dimensions consistent with standard UNF fastener specifications

Compatibility

Designed as a standard UNF hex head cap screw for use in any application calling for a 1/4-28 stainless steel fastener in inch-dimensioned assemblies.

Installation Notes

Install using a 7/16-inch hex socket or open-end wrench. Ensure mating threads are clean and free of debris before driving. When pairing with dissimilar metals, verify material compatibility to prevent galvanic corrosion. Power down or de-energize any equipment before accessing fastener locations on live panels or electrical enclosures.
