Heavy Duty Coiled Spring Pins
End View
For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
All pins meet ASME specifications for material and dimensions. Metric pins also meet ISO 8748 specifications.
Steel pins offer good strength.
18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.
420 stainless steel pins resist wear as well as corrosion. They are magnetic. Those that are passivated offer added protection against corrosion and oxidation.
