Standard: DIN EN ISO 13918 – Type ISA
Materials: Copper-plated steel 4.8 / 1.4301 / 1.4541 / 1.4571 / 1.5415 (16Mo3)
Ground point on one side
No aluminium ball – flux-free welding
Product description – ISA
The BEARFIX® ISA insulation pin is designed for fastening insulation materials to metal structures by drawn arc stud welding.
The ground point on one side facilitates penetration of the insulation where installation is consistently carried out from one direction.
The pin normally welds without a ceramic ferrule and does not use an aluminium ball. After welding, the insulation is retained using Type R or Type W clips.
