Value Collection 208791B Hex Head Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 208791B is a 1/2-13 x 3-1/2 inch hex head cap screw manufactured from 18-8 stainless steel. It features a Unified National Coarse (UNC) thread standard and a 3/4 inch hex drive. The 18-8 stainless steel construction provides solid corrosion resistance for general industrial, mechanical, and structural fastening applications. Length is measured under the head. This fastener is installed by maintenance technicians, pipefitters, millwrights, and general mechanical contractors working across a wide range of trade applications.

This hex head cap screw suits residential and commercial maintenance, equipment assembly, and structural connections where corrosion resistance is a priority. The 1/2-13 UNC thread pitch is one of the most common heavy-duty fastener sizes used in industrial equipment, HVAC frameworks, pump assemblies, and piping support structures. It is sold individually but requires a minimum order quantity of 5 units.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 1/2-13 UNC thread for compatibility with standard inch-system tapped holes and nuts
• 3-1/2 inch length under head for deep fastening applications
• 3/4 inch hex drive accepts standard hex sockets and open-end wrenches

Installation Notes

Install using a 3/4 inch socket or open-end wrench. Follow equipment manufacturer torque specifications for the application and material being fastened. Ensure mating threads are clean and free of debris before installation. Use appropriate thread lubricant or anti-seize compound when fastening into dissimilar metals to prevent galling of stainless threads.
