Value Collection 592385PS Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 592385PS is a partially threaded hex socket cap screw designed for fastening applications that require a strong, corrosion-resistant connection. Sized at 1/2-13 UNC with a 5-inch length under the head, this screw is driven with a 3/8-inch hex (Allen) key. The fastener is manufactured from 18-8 austenitic stainless steel (Material Grade A2) and left uncoated with a bright finish, making it well suited for environments where corrosion resistance is a priority. Machinists, maintenance mechanics, and industrial assembly technicians are the primary installers.

This cap screw is used across a wide range of industrial, mechanical, and structural fastening applications. Partial threading provides a strong clamping zone along the unthreaded shank, making it appropriate for bolted joints that require controlled clamping force and precision alignment. It is commonly found in machine frames, fixtures, tooling, and general mechanical assemblies in both light and heavy industrial settings.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard unified coarse thread nuts and tapped holes
• 5-inch length under head provides extended reach for thicker material stackups
• Partially threaded shank improves clamping performance and shear strength in bolted joints
• 18-8 austenitic stainless steel (Grade A2) offers solid corrosion resistance without plating
• Bright/uncoated finish maintains dimensional consistency and suits clean-room or food-adjacent environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed for use in standard 1/2-13 UNC tapped holes or with matching 1/2-13 UNC hex nuts. Suitable as a direct replacement or upgrade in any application requiring an ASME/ANSI B18.3 and ASTM F837 compliant socket cap screw.

Installation Notes

Installation is performed by machinists or maintenance personnel using a 3/8-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound based on service conditions when working with stainless steel to reduce the risk of galling. Follow applicable torque specifications from ASME or fastener manufacturer guidelines for 1/2-13 UNC stainless steel fasteners.
