Inch Slotted Tension Pins (Roll Pins)

Multi-purpose, non-threaded, versatile

Simplify product design, increase product reliability, reduce production costs and rejection losses

The slotted tension pin is a multi-purpose, non-threaded, versatile and economic fastener. These hollow cylinders are slit longitudinally over their entire length to permit compression during insertion, which gives them a unique, self-locking quality. It is a fastener which not only simplifies design but reduces assembly and production costs, particularly since it can be installed in a single operation.

The combination of material, hardness, and design provides a stronger joint than many of the solid steel pins, taper pins, or grooved pins of like diameter.

Chamfered edges facilitate insertion without disrupting the hole diameter or tolerance in any way. Vogelsang slotted tension pins are offered in several materials, the most common being high carbon spring steel thru-hardened for resilience and wear resistance.

Tension pins can be manufactured with special slot designs per your specification, giving you full control over your product design.

Our engineers are available to help you create precisely the part you need. Perfect for unique applications or when you’re looking for a more reliable, cost-effective solution.
