THE CHOICE - ASME OR ISO SPIROL produces Slotted Pins to both the American National Standard, ASME B18.8.4M, and the International Standard, ISO 8752 (EN 28752). It is our recommendation that you consider ASME pins for all new applications and for your current applications if you are experiencing insertion problems or performance failures. Our recommendation is based on these important advantages of ASME pins: • Lower insertion force as a result of the smaller free diameter of the pin in relation to the nominal hole. The pin is securely retained in the hole based on increased wall thickness, higher...

TECHNICAL INFORMATION Shear Strength The shear test procedure is set forth in ISO 8749, ASME B18.8.2, ASME B18.8.4M, SAE J496, and NASM 10971, which are identical in substance. Shear values specified will only be obtained under the conditions noted in the referenced standards. Of special note: • The clearance at the shear plane cannot exceed 0.15mm or .005”. • The hole has to be the nominal pin diameter (tolerance H6) with a hardness of not less than HV 700. • The shear planes have to be at least one pin diameter from each end, and at least two diameters apart. • ISO 8752 pins are shear tested...
