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.
Cold Headers Inc. has supplied specialty industrial fasteners since 1962. Our catalog helps engineers, distributors, maintenance teams, and purchasing professionals locate exact sizes, uncommon lengths, and difficult-to-find tension pins without unsupported inventory claims.

N/A
1/16 x 3/16 Tension Pin (Slotted Spring Pin) is a spring steel roll pin for economical retention in a drilled hole. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving. Common uses include hinge and pivot joints, covers, and small linkage assemblies, where the pin retains parts without a threaded fastener. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin. Cold Headers has supplied specialty fasteners since 1962 and helps buyers confirm exact pin sizes for maintenance or production requirements. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record. Technical Highlights

N/A
1/16 x 1/4 Tension Pin (Slotted Spring Pin) is a hollow, headless spring pin with a slot running along its length. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving. This size is often reviewed for handles, knobs, and control levers when a self-retaining driven pin is specified. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin. Cold Headers supports hard-to-find pin sourcing, including uncommon lengths and exact diameter-length combinations. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record. Technical Highlights

N/A
1/16 x 5/16 Tension Pin (Slotted Spring Pin) uses spring action to hold itself in a prepared hole without an added head. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. For this diameter, the free OD is 0.066-0.069 in. against a recommended hole of 0.062-0.065 in., so the oversize is intentional. For shaft-to-hub retention, light drives, or spacer assemblies, check the drilled-hole range, pin length, and access for driving the pin squarely. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin. For repair operations, distributors, and OEM sourcing, Cold Headers can help match the item number, diameter, length, and standard. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record. Technical Highlights

N/A
1/16 x 3/8 Tension Pin (Slotted Spring Pin) is formed oversize before installation so the slotted body can compress as it is driven. The catalog term is tension pin, while many drawings use slotted spring pin and many shops say roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving. In latch mechanisms, lock hardware, and service doors, the headless form keeps the joint compact after installation. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin. Cold Headers brings long-running industrial fastener experience to tension-pin quoting, cross-checking, and size confirmation. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record. Technical Highlights

N/A
1/16 x 7/16 Tension Pin (Slotted Spring Pin) is also known as a slotted spring pin or roll pin in engineering and shop-floor terminology. The catalog term is tension pin, while many drawings use slotted spring pin and many shops say roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving. Common uses include agricultural equipment linkages, outdoor mechanisms, and repair assemblies, where the pin retains parts without a threaded fastener. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin. Since 1962, Cold Headers has helped industrial buyers locate specialty pin and socket-product configurations.
