Value Collection 199504 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 199504 is a partially threaded hex socket cap screw designed for medium-to-heavy fastening applications where a clean, recessed drive is required. Sized at 1/2-13 UNC thread with a 2-1/2 inch length under head, it accepts a 3/8 inch hex (Allen) drive. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, chemical-exposed, or outdoor environments. It is suited for mechanical assemblies, structural brackets, equipment mounting, and general industrial fastening where standard hex cap screws are not practical due to tool-clearance constraints.

This screw is appropriate for use in industrial, commercial, and trade settings where stainless steel fasteners are specified for corrosion resistance. Typical applications include HVAC equipment mounting, plumbing fixture brackets, pool and water treatment equipment frames, and general mechanical assemblies. The partially threaded shank provides a clamping shoulder that resists fastener loosening under vibration or dynamic loads. Installation is performed using a standard 3/8 inch hex key or hex driver bit.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard tapped holes and nuts
• 2-1/2 inch length under head accommodates thicker material stacks
• Partial threading provides a bearing shoulder for tight clamping and vibration resistance
• 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• 3/8 inch hex socket drive allows use in recessed or tight-clearance installations

Compatibility

Designed as a standard-dimension 1/2-13 UNC hex socket cap screw suitable for any application requiring that thread size, drive type, and material specification.

Installation Notes

Installation is performed by a mechanic, millwright, or trade technician using a 3/8 inch hex key or powered hex driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound when joining stainless steel to stainless steel components to prevent galling. Torque to the fastener specification appropriate for the joint design and material being fastened.
