Professional Applications & Engineering Value

This 1/4"-10 partially threaded hanger bolt is engineered to address common challenges in wood applications, such as furniture assembly, structural framing, and overhead hanging systems. The zinc yellow-chromate plated steel construction offers superior corrosion resistance, preventing rust and extending service life in moisture-prone settings. Its eye bolt design with a 3/16" diameter facilitates easy attachment of cables or hooks, while the pointed tip ensures straightforward installation without pre-drilling in many wood types. By combining a right-hand thread and precise 10 TPI, it minimizes installation time and enhances load-bearing reliability, making it a go-to choice for industrial and construction projects requiring durable, compliant fasteners.

Specification Summary & Compliance

This hanger bolt adheres to ASME B18.2.1 and ASTM B633 standards, ensuring dimensional accuracy and material consistency. It features a 1/4" screw diameter with a partial thread length of 1-1/2" and 10 threads per inch in a right-hand direction, suitable for standard wood fastening. The zinc yellow-chromate plating meets common industry requirements for corrosion protection, and the product is designed for reliable use in wood-based applications without specific hardness ratings, focusing on practical durability and compliance.
