Overview
CSK Bolt for Crushers
Heavy-duty countersunk (CSK) bolts specially manufactured for crusher liner and jaw plate fastening. The flat conical head seats flush within the countersunk hole of the liner, eliminating any protruding bolt head that would be struck and destroyed by feed material. Available in high tensile grades 8.8 and 10.9 with hex socket or square neck drive. Manufactured in alloy steel with black oxide and HDG finishes. Compliant with ISO 10642 and DIN 7991 standards for use in jaw crushers, cone crushers, impact crushers, and VSI machines.
