Value Collection R63038843 Hex Head Cap Screw 1/2-20

Product Description

The VALUE COLLECTION R63038843 is a hex head cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. Manufactured from 18-8 stainless steel, it offers reliable corrosion resistance in wet, outdoor, and mildly chemical environments. The fastener carries a 1/2-20 UNF (Unified National Fine) thread, which provides greater thread engagement and improved resistance to loosening under vibration compared to coarse-thread equivalents. The 1 inch length under head and 3/4 inch hex drive allow for standard socket or wrench installation. This screw is suited for use by mechanics, pipefitters, electricians, and general tradespeople working with inch-standard fasteners.

This cap screw is appropriate for residential and light commercial applications where corrosion resistance matters, such as plumbing equipment mounting, HVAC unit assembly, electrical enclosure hardware, and pool equipment installation. The fine-thread UNF specification makes it a common choice in precision assemblies and retrofit situations where thread stripping risk must be minimized. It is sold individually, with a minimum order quantity of 50 pieces per order.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• 1/2-20 UNF fine thread provides higher thread count per inch for improved fastening strength
• 1 inch length under head suits standard bracket and flange mounting applications
• 3/4 inch hex drive compatible with standard sockets and combination wrenches
• Inch measurement system for compatibility with standard US trade tooling

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use in any application requiring a 1/2-20 UNF thread pattern and 18-8 stainless steel material grade.

Installation Notes

Installation requires a 3/4 inch wrench or socket driver. Ensure mating threads are clean and free of debris before installation. Do not mix stainless steel fasteners with dissimilar metals in high-moisture environments without appropriate isolation to prevent galvanic corrosion. Apply anti-seize compound if the fastener will be exposed to prolonged moisture or high-temperature cycling.
