Value Collection R40684207 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R40684207 is a hex socket cap screw designed for secure fastening in applications that require high corrosion resistance and reliable clamping force. It features a 1/2-13 UNC thread size and measures 3.5 inches under the head. The drive type is a 3/8 inch internal hex socket, which accepts a standard hex key or Allen-type driver. Constructed from 18-8 stainless steel, this fastener resists rust and corrosion in wet, chemical, or outdoor environments. It is suited for use in mechanical assemblies, equipment frames, and structural connections where stainless fasteners are specified by design or code.

This cap screw is appropriate for general industrial, mechanical, and maintenance applications. It is commonly installed in HVAC equipment frames, pump and motor mounts, piping supports, and general fabrication work where a socket-drive fastener is preferred over a hex-head bolt. The 1/2-13 UNC thread is a standard coarse-thread designation widely used across trade and industrial settings. Installations requiring corrosion-resistant hardware in marine, food-service, or outdoor environments are typical use cases for 18-8 stainless fasteners of this type.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 3.5 inch length under head provides substantial clamping depth for thick assemblies
• 3/8 inch hex socket drive accepts standard Allen keys and hex-bit drivers
• 18-8 stainless steel construction offers corrosion resistance in wet and chemical environments
• Low-profile socket cap head allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use wherever a coarse-thread stainless steel socket cap fastener of this size and length is specified.

Installation Notes

Installation is performed with a 3/8 inch hex key or an appropriately sized hex-bit driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply appropriate torque per the assembly specification and avoid overtightening, which can strip threads or crack the fastener head in stainless steel grades. For structural or pressure-boundary applications, follow applicable mechanical codes and the equipment manufacturer's fastener requirements.
