Basic Specifications
◎ External and internal diameters of Metric screw threads must meet the requirement of ISO 965-2:1998.◎ External and internal diameter of British Standard screw threads must meet the requirement of ASME B1.1:2003.
◎ External threads of counterparts must meet the tolerance of 6g ring gauge. Internal threads of counterparts must meet the tolerance of 6H bolt gauge.
◎ For internal threaded counterpart, chamfer processing is necessary and it should not have any sharp burr.
◎ The coating length should be at least 0.8d, and the coating design should be based on the actual locking position on the counterpart.
◎ The design of self-locking torque is mainly based on DIN 267-27 (with preload) specification. Please consult us in advance for any special requirement.
◎ During the locking process, fasteners and its counterparts cannot be contaminated by any oil and solvent.
Chemical Adhesive Inspection Specification: DIN 267-27
DIN stands for Deutsches Institut für Normung. It is a very important standardization organization based in Germany. Many of its standards are adopted by EN and ISO, which have been widely used internationally.Please enter detailsSelf-Locking Torque Inspection Specification for NYLOK®
