Brand FABORY
Material Stainless spring steel
Info
  • Dimensions d1 and d2 in above table are before mounting.
  • The type of austenitic stainless spring steel is at the manufacturer’s discretion and may vary from the steel types stated in ISO 3506.
  • V = minimum shear strength, double, in kN.
  • The recommended tolerance class for the accommodating hole diameter d (nominal) is H12, except for d 1,2, where H10 is recommended.Special features of coiled spring-type straight pins (spiral pins):
    • These pins are used for connections or the positioning of two or more parts and may also be used as shafts and hinge-, stop- or carrierpins, and are easily disassembled.
    • Thanks to their spiral shaped cross section (approximately 2.1/4 coils) these pins are very flexible and suitable for repeated use with dynamic loads. Equal stress distribution throughout their cross section against the hole wall produces a good press fit, which can absorb shear forces unaffected by the direction.
    • The pins are chamfered at both ends, so they can easily be inserted and installed automatically.
