Value Collection MP30594 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP30594 is a 3/8-16 hex head cap screw made from Grade 316 stainless steel. It measures 1-1/2 inches under the head and features a Unified National Coarse (UNC) thread form. The 9/16-inch hex drive allows installation with standard wrenches or sockets. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making this fastener well suited for wet, marine, chemical-exposure, and outdoor environments. Plumbers, pipefitters, HVAC technicians, and electricians commonly reach for 316 stainless hardware when code or service conditions demand a higher corrosion threshold than carbon or standard stainless steel can deliver.

This cap screw is appropriate for use in residential and commercial applications where corrosion resistance is a primary concern. Typical installation scenarios include pipe flange connections, equipment mounting in corrosive environments, pool and spa mechanical installations, and marine or coastal construction. The 3/8-16 UNC thread is one of the most widely used fastener sizes in trade work, and the 1-1/2-inch grip length fits a broad range of standard flange and bracket thicknesses.

Key Features

• Grade 316 stainless steel construction for elevated corrosion resistance in harsh or wet environments
• 3/8-16 UNC thread form compatible with standard 3/8-16 nuts and tapped holes
• 1-1/2-inch length under head suits common flange and bracket applications
• 9/16-inch hex drive accepts standard wrenches and sockets
• Inch measurement system throughout for straightforward fitment verification

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw for use with any 3/8-16 threaded nut, insert, or tapped hole requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, HVAC technicians, or electricians depending on the application. Always ensure mating threads are clean and free of debris before driving the fastener. When installing stainless steel fasteners into stainless steel tapped holes, apply an anti-seize compound to prevent galling. Verify that the fastener grade and material are appropriate for the service environment and any applicable code requirements before installation.
