Heating fastener blanks for thread rolling

Overview

Rolling a thread into a heated fastener (instead of milling or grinding the thread) has many advantages. We have developed a specially-designed heat station for this application which can be vertically clamped to the thread-rolling machine and then easily adjusted to match the length of the fastener material being heated.

Benefits

• no burs, jagged edges or shavings
• faster cycle times and extended tool life with preheat step
• stronger and more fatigue-resistant threads

Thread Patching

Thread patching is a process of curing paint or powder coating that has been applied to a section of the fastener threads to prevent loosening of the fastener due to vibration.

Benefits

• superior cure for paint or powder coating to fastener treads
• highly localized heat directed only to the area that needs curing
• no lengthy warm up or cool down cycles
• faster production rates and higher yields
• parts can be individually monitored for quality
