Value Collection MP30595 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP30595 is a partially threaded hex head cap screw designed for fastening applications that require corrosion resistance and mechanical strength. Sized at 3/8-16 UNC thread with a 1-3/4 inch length under head, this fastener is manufactured from Grade 316 stainless steel with no additional coating. Grade 316 stainless provides enhanced resistance to chlorides and corrosive environments compared to Grade 304, making it a common choice in marine, chemical, food service, and outdoor installations. The partially threaded shank allows for a clamping grip on the unthreaded portion, which helps prevent joint loosening under load.

This fastener is used across a wide range of trade applications including HVAC equipment mounting, plumbing fixture attachment, electrical enclosure assembly, and pool equipment installation. The 3/8-16 UNC thread pattern is one of the most common coarse-thread sizes in inch-system mechanical assembly. Partially threaded cap screws in this size are regularly used where two components of differing thickness must be drawn together with a defined grip zone, such as structural brackets, pump housings, and equipment frames exposed to moisture or outdoor conditions.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chloride-rich environments
• Partially threaded shank provides a defined grip zone for secure clamping of mating components
• 3/8-16 UNC coarse thread for broad compatibility with standard inch-system tapped holes and nuts
• Uncoated finish maintains dimensional accuracy and avoids coating-related galling on stainless fasteners
• 1-3/4 inch length under head suits moderate-depth fastening in brackets, flanges, and equipment panels

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes or with matching 3/8-16 hex nuts and washers in inch-system mechanical assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation is typically performed by a qualified mechanic, plumber, or electrician using a standard hex wrench or socket driver. Always ensure the mating threads are clean and free of debris before driving to avoid galling, which is a common issue with stainless fasteners. Do not use an impact driver at full torque without a torque-limiting socket, as stainless steel cap screws are susceptible to seizing and shear. Follow applicable mechanical or structural codes for the specific application.
