Tension pins are hollow spring fasteners designed to align, retain, secure, or position components in mechanical assemblies. Their spring action allows the pin to compress during installation and expand within the receiving hole to create a secure interference fit. Tension pins are widely used in machinery, power transmission equipment, agricultural equipment, automation systems, industrial tooling, pumps, motors, gearboxes, fixtures, maintenance repairs, and OEM manufacturing.
Commonly referred to within the fastener industry as spring pins or roll pins, tension pins are selected where dependable retention and ease of installation are important. They are frequently used to secure gears, hubs, collars, levers, cams, shafts, pulleys, handles, hinges, and other machine components without requiring threads or separate locking hardware. Proper selection should consider the pin diameter, overall length, hole size, mating material, installation method, and the functional requirements of the completed assembly.
Cold Headers supplies industrial tension pins in a broad range of inch sizes and lengths, including standard and difficult-to-source configurations. Individual product pages provide verified diameter, length, and other engineering dimensions where available to assist engineers and purchasing professionals with accurate product selection.
Begin by confirming the required pin diameter and overall length. Review the receiving hole dimensions, mating materials, installation method, operating environment, and assembly requirements before selecting a pin. Final product selection should reflect the mechanical and functional requirements of the completed assembly.

Pull dowel pins are precision locating pins manufactured with an internally threaded hole that allows the pin to be removed using a mating screw or extraction tool. They are designed to provide accurate alignment and repeatable positioning of machine components while simplifying maintenance, inspection, and replacement. Unlike standard press-fit dowel pins, pull dowel pins can be extracted without prying against surrounding components, making them well suited for assemblies that require periodic disassembly.
Pull dowel pins are commonly used in tooling, fixtures, dies, molds, automation equipment, machine bases, jigs, inspection equipment, production machinery, and OEM assemblies where precise alignment is critical. Their precision-ground outside diameter helps maintain consistent component location while the threaded extraction feature reduces the risk of damage during servicing.
Proper dowel pin selection should consider pin diameter, overall length, hole tolerances, fit requirements, mating materials, and expected maintenance intervals. Individual product pages provide verified pin diameter, overall length, internal thread size where applicable, and other engineering dimensions to assist engineers and purchasing professionals in specifying the correct locating pin.

0.001 oversize dowel pins are precision locating pins manufactured with an outside diameter that is 0.001 inch larger than the corresponding standard nominal size. They are commonly selected when repairing worn locating holes, restoring alignment, or accommodating applications where an oversize precision locating pin is specified. These pins help maintain accurate positioning of mating components in industrial machinery, tooling, fixtures, dies, molds, and OEM equipment.
Oversize dowel pins are frequently used during equipment rebuilding, machine maintenance, fixture repair, and precision assembly operations where a standard-size dowel pin no longer provides the required fit. Typical applications include locating machine components, aligning fixtures, positioning dies, securing tooling, indexing assemblies, and maintaining repeatable alignment between mating parts.
Proper pin selection should consider the required oversize diameter, overall length, receiving hole dimensions, fit requirements, mating materials, and assembly method. Individual product pages provide verified pin diameter, overall length, and other engineering dimensions where available to assist engineers and purchasing professionals in selecting the correct locating pin.

18-8 stainless steel standard dowel pins are precision locating pins designed to accurately align, position, and retain mating components in mechanical assemblies. Their precision-ground cylindrical profile provides repeatable alignment for tooling, fixtures, dies, molds, machinery, and production equipment while offering the corrosion resistance of 18-8 stainless steel. Standard dowel pins are widely used wherever consistent positioning and reliable component registration are essential to assembly performance.
Manufactured from 18-8 stainless steel, these dowel pins provide general corrosion resistance for many industrial environments exposed to moisture, humidity, or routine washdown. They are commonly specified for machinery, automation equipment, fixtures, jigs, conveyors, instrumentation, maintenance repairs, food processing equipment, and OEM manufacturing where stainless steel construction is preferred.
Proper dowel pin selection should consider pin diameter, overall length, receiving hole dimensions, fit requirements, mating materials, installation method, and service conditions. Individual product pages provide verified pin diameter, overall length, and additional engineering dimensions where available to assist engineers and purchasing professionals in selecting the correct locating pin.
