Calibrated Shear Pins | pack of 250

Pin Brinell Shear Pins. Replacement shear pins for use with all Pin Brinell Hardness Testing kits. Includes calculations for use with the CP-3 and CP-3A indenters on all ferrous metal applications including rolled, forged and cast steels and alloys. Hardness calculation equivalent to the standard HB-30 Brinell formula. Complete with Brinell chart and Pin Brinell operating instructions. Supplied in packs of 250 pins.

A calibrated shear pin fits into the Pin Brinell housing. The shear pin comes into contact with the indenter and prevents the indenter from recessing back into the Pin Brinell housing. The indenter is positioned against the sample. Load is applied using either an impact hammer for impact testing or through the use of a C-clamp
for static load testing. When the load is applied which exceeds the shear pin’s shear value, the pin breaks. The load to indentation size ration provides a displacement that is equivalent to the most common Brinell test (3000 kgf, 10 mm Ball) and the Brinell values arrived at using the standard Brinell formula. The diameter of the resulting indentation on the sample is then measured using a Brinell scope, such as our Pocket or HiLight models, or using our B.O.S.S. optical scanning system.
