Value Collection 63537 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 63537 is a hex socket cap screw designed for fastening applications that require corrosion resistance and reliable clamping strength. Threaded at 3/8-16 UNC, it features a 1-inch length under head and accepts a 5/16-inch hex drive. The fastener is manufactured from 316 stainless steel, which provides superior resistance to chlorides, moisture, and chemical exposure compared to standard 304-grade material. Machinists, pipefitters, plumbers, and general trade mechanics use this type of cap screw where a low-profile socket head is preferred over a standard hex bolt head, especially in tight clearance installations.

This cap screw is suited for use in marine, industrial, and process-piping environments where corrosion is a primary concern. The 3/8-16 UNC thread form is a standard coarse-thread pitch widely used in structural and mechanical assemblies across commercial and residential trades. Typical applications include equipment mounting, bracket fastening, and mechanical component assembly where a flush or recessed fastener head is required. The socket drive style allows installation with a hex key or Allen driver in areas where a wrench cannot swing freely.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 1 inch length under head for moderate grip-range fastening
• 5/16-inch hex socket drive for use with Allen keys or hex bit drivers
• 316 stainless steel construction for enhanced corrosion and chloride resistance
• Low-profile socket cap head suits tight-clearance and recessed installations

Compatibility

Designed as an OEM-style replacement or standard fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 1-inch length under head in 316 stainless steel.

Installation Notes

Installation is performed with a 5/16-inch hex key or a matching hex bit and driver. Ensure mating threads are clean and free of debris before installation. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without an appropriate isolating barrier. Follow applicable mechanical or piping codes for the torque class and thread engagement requirements of the specific assembly.
