Value Collection 1-S-37F-450 Hex Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 1-S-37F-450 is a hex socket cap screw designed for applications requiring a precise, high-strength threaded fastener in a compact head profile. Machined to a 3/8-24 UNF thread spec, this screw measures 4.5 inches in length under the head and is driven with a 5/16-inch hex key. Constructed from 18-8 stainless steel with a bright, uncoated finish, it offers reliable corrosion resistance in wet, chemical-exposed, or outdoor service environments. Trade professionals install this type of fastener in HVAC equipment frames, plumbing fixtures, electrical enclosures, and mechanical assemblies where a flush or low-profile head is required and access is limited to an Allen-drive tool.

This screw is suited for light industrial and commercial mechanical work, including equipment mounting, panel assembly, and bracket fastening. The 3/8-24 UNF thread is a fine-pitch designation, offering greater thread engagement per inch compared to coarse UNC threads. That makes it appropriate for applications involving vibration, thin-wall materials, or precise clamping loads. Installers working on HVAC units, pump assemblies, pool equipment enclosures, and conduit support structures will find this a standard-service fastener for general mechanical connections.

Key Features

• 3/8-24 UNF fine-pitch thread for high engagement and vibration resistance
• 4.5-inch length under head suits deeper through-bolt and standoff applications
• 5/16-inch hex drive allows use with standard Allen keys and hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in wet environments
• Bright uncoated finish maintains dimensional accuracy and thread tolerance

Compatibility

Designed as a general-purpose hex socket cap screw for mechanical assemblies requiring a 3/8-24 UNF fine-thread fastener with a 4.5-inch length under head and 5/16-inch hex drive.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using a calibrated hex key or Allen-drive bit. Verify thread engagement and mating nut or tapped-hole compatibility before final torque. Stainless steel fasteners are prone to galling — apply an appropriate anti-seize compound to the threads when inserting into stainless or aluminum tapped holes. Always de-energize and isolate equipment before accessing any mechanical assembly where fasteners are being replaced or serviced.
