Value Collection R82222633 Hex Cap Screw 3/8-16 X 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R82222633 is a 3/8-16 hex head cap screw sized 5/8 inches under the head, manufactured from 18-8 stainless steel with no coating applied. The 3/8-16 thread designation indicates a 3/8-inch nominal diameter with 16 threads per inch on a UNC (Unified National Coarse) thread form. The 18-8 stainless alloy provides solid corrosion resistance, making this fastener well-suited for wet, outdoor, or mildly corrosive environments. It is installed by mechanical contractors, plumbers, electricians, HVAC technicians, and general tradespeople wherever a standard hex-drive stainless fastener is required.

This screw is a general-purpose inch-series fastener appropriate for light structural, mechanical, and equipment-mounting applications across residential and commercial work. Its uncoated finish means it ships as-machined with no additional surface treatment, which suits applications where galvanic compatibility with stainless hardware is needed. This SKU is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 3/8-16 UNC thread form — compatible with standard 3/8-16 nuts, inserts, and tapped holes
• 5/8-inch length under head for consistent grip-length control in standard assemblies
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Uncoated finish — no plating or coating that could interfere with galvanic compatibility
• Meets multiple MS fastener standards for use in applications requiring documented compliance
• Minimum order quantity of 10 units per order

Installation Notes

Install with a standard hex wrench or socket sized for a 3/8-16 hex head cap screw. De-energize or shut off any system before fastening components in electrical or mechanical enclosures. Use stainless nuts and washers where possible to avoid dissimilar-metal galvanic corrosion. Do not overtighten stainless fasteners, as 18-8 alloy is susceptible to galling — apply an anti-galling lubricant when torque requirements are high.
