Value Collection MP92366 Hex Cap Screw 1/2-13 X 4 in 18-8 Ss

Product Description

The VALUE COLLECTION MP92366 is a 1/2-13 x 4-inch hex head cap screw manufactured from 18-8 stainless steel with a Unified National Coarse (UNC) thread form. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch. The 18-8 stainless steel grade provides solid corrosion resistance in a wide range of service environments, making it a dependable fastener choice where carbon steel is not appropriate. The hex drive measures 3/4 inches across flats. This fastener is sold individually with a minimum order quantity of 10 pieces and is measured by length under head.

This hex cap screw is suited for general mechanical assembly, structural connections, and equipment fabrication in applications where corrosion resistance is a priority. Typical use cases include plumbing equipment mounting, HVAC bracket and frame assembly, pool and water treatment equipment, and marine-adjacent installations where moisture exposure is a factor. Licensed tradespeople and maintenance technicians commonly specify 18-8 stainless hardware in these environments to reduce fastener corrosion and extend service intervals.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and chemical-adjacent environments
• 1/2-13 UNC thread form for broad compatibility with standard 1/2-inch tapped holes and nuts
• 4-inch length under head for applications requiring extended grip length
• 3/4-inch hex drive accepts standard sockets and wrenches
• Inch measurement system with UNC thread standard

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use in any application requiring a 1/2-inch coarse-thread fastener in 18-8 stainless steel.

Installation Notes

Install using a 3/4-inch socket or open-end wrench. Ensure the mating tapped hole or nut is also rated for 1/2-13 UNC thread engagement before installation. When installing stainless steel fasteners, apply an appropriate anti-seize compound to reduce the risk of galling during tightening. Follow the applicable mechanical or structural code requirements for the equipment being serviced.
