GUIDE FOR USE

	Hole tolerance For the diameter, the tolerance range H 10 forms the basis for coiled pins with nominal diameter d1 up to 1.2mm and H12 for pins with nominal diameter d1 greater than 1.2 mm. The nominal diameter of the coiled pin is also the nominal diameter of the respective location hole. When using the coiled pin as a hinge pin care should be taken that the loose fit is in the central part and the tight fit in the fork part. The suitable hole tolerance is best determined by testing. Inserting the coiled pins. Inserting the coiled pin is commonly done manually, by means of a hammer and steel mandrel or automatically with pneumatic or hydraulic mounting apparatus. So that trouble free inserting is guaranteed, the following points should be observed: The edge of the hole should be chamfered. Chamfer for hardened holes: 600, otherwise less than 90o When inserting or removing the coiled pin with a steel mandrel, the diameter of the mandrel should be the same as dimension d2 as per the tables on pages 2 and 3 so that contact over the whole surface of the pin is maintained.

	Areas of use They replace rivets, screws, bolts and similar fastening elements. The SFP coiled pin provides an inexpensive manufacturing solution on account of efficient hole production (tolerance range H12), simple and quick processing or automatic mounting and low component costs. The SFP coiled pin can be used as a fastening pin, positioning pin, stop pin, driving pin and hinge pin.
