Value Collection R57001058 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001058 is a hex socket cap screw engineered for applications requiring a clean, recessed drive profile and reliable clamping strength. Threaded to 3/8-16 UNC specifications, it measures 6-1/2 inches under the head and accepts a 5/16-inch hex key drive. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet or mildly corrosive environments. It is a standard choice for mechanical assemblies, equipment mounting, and structural connections where a flush or countersunk head profile is required by the installation design.

This screw is suited for use in HVAC equipment frames, plumbing fixture mounting, electrical enclosure assembly, and general trade fabrication where 3/8-16 UNC threading is specified. The 6-1/2-inch length under head accommodates applications with substantial material stack-up or through-bolt requirements. The 18-8 stainless steel construction makes it appropriate for indoor and outdoor assemblies where exposure to moisture is a concern. Mechanical contractors, pipefitters, and general tradespeople will find this fastener suitable for a wide range of service and installation tasks.

Key Features

• 3/8-16 UNC thread form for compatibility with standard American coarse-thread fastener applications
• 6-1/2-inch length under head accommodates deep through-bolt and thick-stack assembly configurations
• 5/16-inch internal hex drive accepts standard hex key and Allen-style drivers
• 18-8 stainless steel construction provides corrosion resistance in wet and mildly corrosive environments
• Bright, uncoated finish — no plating that can chip or flake in service
• Socket cap head profile allows installation in confined spaces where a wrench cannot reach the fastener head

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use wherever that thread size and a 6-1/2-inch under-head length are specified in mechanical, HVAC, plumbing, or electrical assembly applications.

Installation Notes

Installation requires a 5/16-inch hex key or socket-style Allen driver. Ensure mating threads are clean and free of debris before driving the fastener. Apply appropriate thread lubricant or anti-seize compound when joining dissimilar metals to prevent galling of the stainless steel threads. Minimum order quantity is 10 units per order.
