The SIOUX CHIEF 874-2N is a nylon bolt with a 1/4-20 thread and a 2-inch length, used in plumbing and mechanical installations where non-metallic fasteners are required. Nylon construction resists corrosion and eliminates galvanic reaction, making this bolt well suited for securing plastic pipe supports, straps, and brackets in wet or chemically active environments. Plumbers, pipefitters, and mechanical contractors reach for this type of fastener when metal hardware would corrode or create electrical continuity issues in the installation.
This bolt is appropriate for residential and light commercial plumbing applications including pipe hanger assemblies, bracket mounting, and equipment securing tasks where a non-conductive, corrosion-resistant fastener is specified. It is a standard 1/4-20 thread pattern, compatible with correspondingly threaded nylon or metal nuts and inserts commonly used in pipe support systems.
Designed as an OEM-style fastener for use with standard 1/4-20 threaded plumbing support hardware, pipe hangers, and bracket assemblies requiring a non-metallic bolt.
Installation is performed by plumbers or mechanical contractors as part of pipe support or equipment mounting work. Shut off any affected systems before disassembling support structures. Nylon fasteners have lower tensile strength than metal equivalents — do not over-torque, as nylon threads can strip or shear under excessive force. Follow local plumbing code requirements for hanger spacing and support loading.
