Value Collection -30604-2X Hex Head Cap Screw 1/2-13 X 4 in

Product Description

The VALUE COLLECTION -30604-2X is a partially threaded hex head cap screw designed for secure bolted connections in demanding applications. Manufactured from Grade 316 stainless steel, it delivers strong resistance to corrosion, pitting, and chemical exposure, making it well suited for wet, marine, or chemically active environments. The fastener measures 1/2-13 thread size with a 4-inch length under the head, and it conforms to Unified National Coarse (UNC) thread standards. It ships uncoated, preserving the natural corrosion-resistant properties of the base alloy. Licensed trades and industrial maintenance technicians install this type of fastener in structural, mechanical, and process equipment assemblies.

This hex head cap screw is appropriate for use in residential, commercial, and industrial settings where stainless steel fasteners are specified. Grade 316 material is commonly called out in coastal construction, food processing, chemical processing, marine hardware, and HVAC or plumbing equipment exposed to moisture or corrosive agents. The UNC thread form is the standard inch-series coarse thread, compatible with standard 1/2-13 nuts and tapped holes. Partial threading allows the shank to act as a shoulder section for applications that require precise positioning or shear loading across the joint interface.

Key Features

• Grade 316 stainless steel construction provides superior corrosion and chemical resistance compared to Grade 304
• 1/2-13 UNC thread form matches standard inch-series nuts and tapped holes
• 4-inch length under head accommodates thicker assemblies and through-bolt applications
• Partial threading leaves a smooth shank section for shear loading and precise joint alignment
• Uncoated finish maintains the natural surface integrity of the 316 alloy
• Minimum order quantity of 25 pieces supports project-quantity purchasing

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use with any 1/2-13 threaded nut or tapped hole conforming to inch-series UNC specifications.

Installation Notes

Installation is performed by qualified mechanics, millwrights, plumbers, or HVAC technicians depending on the application. Use a standard hex wrench or socket sized for a 1/2-inch hex head cap screw, and always confirm thread engagement before applying torque. Inspect the mating nut or tapped hole for corrosion or thread damage before assembly, particularly in replacement or retrofit work. Follow applicable mechanical or structural codes for fastener torque and joint design requirements.
