Value Collection 63538 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 63538 is a hex socket cap screw designed for applications requiring a recessed drive fastener with a clean, low-profile head. Threaded to 3/8-16 UNC coarse pitch, this screw measures 1-1/4 inches under the head and is driven with a 5/16-inch hex key. Constructed from 316 stainless steel, it offers strong corrosion resistance in wet, marine, and chemical-exposure environments. This fastener is a standard choice for mechanical assemblies, equipment framing, and structural connections where a torqued, tamper-resistant socket head is preferred over an external hex configuration.

This screw is suited for use in industrial, commercial, and trade applications where 3/8-16 UNC threaded connections are specified. Common install scenarios include HVAC equipment mounting brackets, plumbing support structures, pump housings, and general mechanical assemblies. The 316 stainless steel grade makes it particularly appropriate for outdoor installations, coastal environments, and any setting where fastener corrosion is a service concern. Licensed tradespeople and maintenance technicians working in corrosive or high-humidity environments typically specify this grade for long-term reliability.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 1-1/4 inch length under head provides adequate grip range for typical bracket and panel thickness
• 5/16-inch hex socket drive accepts standard Allen or hex key sets
• 316 stainless steel construction for corrosion resistance in marine and chemical environments
• Socket cap head style allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard OEM-style replacement or direct-use fastener in any application specifying a 3/8-16 UNC hex socket cap screw with a 1-1/4-inch length under head.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver; use of a torque wrench is recommended for structural connections to meet application specifications. Ensure the mating threaded hole or nut is clean and free of debris before driving. Power down or de-energize any equipment being serviced before fastener removal or replacement. Follow applicable mechanical or structural codes for torque requirements specific to the assembly.
