Overview

The Minerallac Company 54212 is a Hex Head Cap Screw (HHCS) from the 230-233 series, engineered for reliable assembly into tapped holes. Constructed from high-quality silicon bronze (Alloy 651), this fastener offers exceptional corrosion resistance, making it particularly suitable for marine environments such as boat fittings, dock hardware, and underwater equipment. It also performs well in industrial settings where electrical enclosures and machinery are exposed to seawater or chloride-rich conditions. This HHCS features a 5/16-18 coarse thread size, ensuring compatibility with standard tapped holes, and a 3/4-inch length for secure fastening. The 1/2-inch hex head provides ample surface area for tool engagement, facilitating precise torque application and minimizing the risk of cam-out. With a head height of 13/64 inch, it maintains a low profile while delivering structural integrity. The distinctive copper-colored head finish aids in visual identification and develops a protective patina over time, further enhancing its corrosion resistance.
