Value Collection MP30599-3 Hex Head Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION MP30599-3 is a 3/8-16 UNC hex head cap screw manufactured from Grade 316 stainless steel. It measures 3 inches in length under the head and uses a 9/16 inch hex drive. This fastener is suited for bolted connections requiring corrosion resistance in demanding environments. Grade 316 stainless steel provides elevated resistance to chlorides and oxidizing agents compared to standard 304-series material, making it a common choice in wet, marine, or chemical-exposure applications. Licensed trades and maintenance professionals install this type of fastener across mechanical, plumbing, and structural assemblies.

This cap screw is used in industrial, commercial, and marine maintenance applications where a unified coarse thread profile and stainless material are specified. Typical use cases include equipment mounting, pipe flange connections, pump housings, and enclosure hardware where corrosion resistance is a service requirement. The 3/8-16 UNC thread is a widely specified size across HVAC equipment frames, plumbing brackets, and electrical enclosure hardware.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance
• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 3 inches length under head suits medium-depth fastening applications
• 9/16 inch hex drive fits standard hex wrench and socket tooling
• Inch measurement system, UNC thread standard

Compatibility

Designed as a standard inch-series hex head cap screw for use in any assembly calling for a 3/8-16 UNC fastener in Grade 316 stainless steel.

Installation Notes

Installation is performed with a 9/16 inch hex wrench or socket. Ensure mating threads are clean and free of debris before driving. Apply appropriate anti-seize compound when installing stainless fasteners into stainless tapped holes to prevent galling. Follow applicable mechanical or structural specifications for torque requirements based on joint design.
