Value Collection R88434614 Hex Head Cap Screw 1/2-13 X 9 in

Product Description

The VALUE COLLECTION R88434614 is a 1/2-13 x 9 inch hex head cap screw machined from 18-8 stainless steel with no surface coating applied. It features a Unified National Coarse (UNC) thread form and is partially threaded along the shank length. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch. At 9 inches in length under the head, this fastener suits applications requiring a long grip with a smooth unthreaded shank section. Installers in mechanical, plumbing, HVAC, and industrial service work reach for 18-8 stainless hardware where corrosion resistance is a priority.

This screw is suited for general fastening tasks in corrosive or moisture-prone environments, including equipment mounting, pipe support structures, HVAC framework, and mechanical assemblies. The partial threading provides a smooth shank bearing surface useful in applications where the fastener passes through clearance holes before engaging a threaded nut or tapped hole. Residential and light commercial service technicians as well as fabricators handling stainless assemblies will find this fastener appropriate for a wide range of structural and equipment attachment tasks.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Partially threaded shank allows use in applications requiring a smooth bearing surface
• UNC thread form is the most common inch-series thread standard for general fastening
• Uncoated finish maintains base material properties with no added plating or treatment
• 1/2-13 thread size accommodates standard hex nuts, coupling nuts, and tapped holes in the 1/2-inch class
• 9-inch under-head length provides generous grip range for thick assemblies or long-reach applications

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, lock nuts, and tapped holes conforming to inch-series thread standards. Suitable for general mechanical fastening applications where an 18-8 stainless partially threaded hex cap screw is specified.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or service technician using an appropriately sized hex wrench or socket driver. Ensure mating threads are clean and free of debris before assembly. Stainless steel fasteners are susceptible to galling under high-speed or high-torque driving — apply an anti-seize compound and drive slowly by hand until snug before final tightening. Always follow applicable mechanical codes and equipment manufacturer specifications for torque requirements.
