Overview
This industrial-grade steel dowel pin is engineered for high-precision alignment in heavy-duty mechanical assemblies. Designed to maintain strict dimensional accuracy, the component features a robust 1.57-inch diameter and a 2.5-inch length, ensuring reliable performance under significant structural loads. The pin incorporates an M40 thread configuration, facilitating secure installation and removal within threaded receptacles. Manufactured from high-quality steel with an unplated finish, this fastener delivers consistent structural integrity without the need for additional surface coatings or treatments. It is specifically suited for applications where exact positioning and minimal play are critical to operational safety and efficiency.
Key Features
Precision ground to a tolerance of +0.000/-0.001 inches for interference fits Robust steel construction provides high shear strength and durability M40 thread size allows for secure engagement in heavy machinery Unplated finish prevents contamination in sensitive assembly environments 1.57-inch diameter offers substantial load-bearing capacity 2.5-inch length ensures deep engagement for enhanced stability Sold in packages of 50 units to support large-scale production needs

Applications
Heavy machinery assembly and maintenance Precision jig and fixture alignment Automotive manufacturing tooling Aerospace structural component positioning Die casting mold alignment Industrial robotics mounting points Power generation equipment assembly These dowel pins serve as essential components in environments requiring repeatable accuracy and long-term reliability. The tight tolerance specification ensures that once installed, the pin eliminates lateral movement between mating parts, which is vital for maintaining the geometric precision of complex assemblies. The unplated steel surface is ideal for applications where lubricants or adhesives will be applied separately, or where plating could interfere with the precise fit required by the design. By utilizing a standard M40 thread, these pins integrate seamlessly into existing systems designed for metric threading while adhering to imperial dimensional standards for the pin body. This hybrid approach supports diverse manufacturing requirements, making them a versatile choice for global supply chains and domestic fabrication shops alike. The bulk packaging format supports inventory management for facilities running continuous production lines, reducing the frequency of reordering and ensuring that critical spare parts are always available for immediate deployment.
