Value Collection R63036249 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63036249 is a 1/4-20 x 1-1/2 inch hex head cap screw manufactured from Grade 316 stainless steel. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it suitable for wet, marine, chemical-exposure, and outdoor environments. The fastener follows Unified National Coarse (UNC) thread standards and accepts a 7/16 inch hex drive. Length is measured under the head. This screw is commonly installed by plumbers, pipefitters, electricians, HVAC technicians, and general contractors working on corrosion-sensitive assemblies and equipment.

This fastener is used in residential and commercial applications where corrosion resistance is a priority. Typical uses include mounting HVAC equipment, securing plumbing fixtures and pipe supports, electrical enclosure assembly, pool and spa equipment installation, and marine or coastal construction. Grade 316 stainless is specifically well-suited for chloride-rich environments such as pool mechanical rooms and coastal installations where standard carbon steel fasteners would corrode rapidly.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 1-1/2 inch length under head for moderate grip range
• 7/16 inch hex drive accepts standard wrenches and sockets
• Inch measurement system, length measured under head

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw compatible with any tapped hole or nut conforming to Unified National Coarse thread standards in the 1/4-20 designation.

Installation Notes

Install using a 7/16 inch open-end wrench, box wrench, or socket. Ensure mating threads are clean and free of debris before installation. When installing into dissimilar metals, consider the potential for galvanic corrosion and use appropriate isolation hardware. Power down or de-energize any equipment before fastening into or adjacent to electrical enclosures.
