Value Collection 198574 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 198574 is a 1/2-13 UNC hex socket cap screw manufactured from 18-8 stainless steel with a fully threaded shank. The fastener measures 2 inches in length under the head and is driven with a standard hex (Allen) key. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch in the Unified National Coarse thread standard. The 18-8 stainless steel construction provides solid corrosion resistance in wet and moderate chemical environments. This screw is appropriate for mechanical assemblies, structural connections, and equipment fabrication where a flush or recessed fastener head is required.

Hex socket cap screws in this size range are commonly used in industrial, commercial, and trade applications including HVAC equipment frames, plumbing fixture mounting, electrical enclosures, and general mechanical assemblies. The fully threaded configuration makes the 198574 well suited for shorter-length clamping applications or through-bolt installations where thread engagement is needed along the full fastener length.

Key Features

• 1/2-13 UNC thread form for compatibility with standard SAE-spec nuts and tapped holes
• Fully threaded shank provides maximum thread engagement across the full 2-inch length under head
• 18-8 stainless steel construction resists corrosion in wet and mildly corrosive environments
• Hex socket drive allows installation in recessed or tight-clearance locations
• Minimum order quantity of 5 units ensures adequate supply for multi-fastener applications

Compatibility

Designed for use in any application requiring a 1/2-13 UNC threaded fastener with a hex socket drive, including standard SAE-spec tapped holes and nuts of matching thread specification.

Installation Notes

Installation requires a properly sized hex key or Allen socket driver; use of an incorrect driver size can damage the socket recess. Apply the appropriate torque for 1/2-13 stainless steel fasteners per the project or equipment specification to avoid galling, which is common with stainless hardware. Anti-seize compound is recommended on stainless threads to reduce the risk of thread galling during installation and future removal. Follow all applicable mechanical and structural codes for the specific assembly.
