MATE Precision Tooling, represented in Australia by Advanced Sheetmetal Technologies , has released HexLock tooling, a system that fabricates forms that align with and hold hexagon head bolts. This fabricating option for punch presses provides a reliable and secure method of holding threaded fasteners in sheet metal for assembly.
When formed, the HexLock accepts either a hexagon nut or the head of a hexagon bolt. A nut allows sheet metal parts to be assembled with a corresponding bolt from the reverse side of the part. Alternatively, the head of a bolt can be installed with the thread protruding through the sheet metal. In either mode the fastener is gripped securely between the punched forms to prevent nut rotation as the assembly is torqued together.
HexLock tooling is designed for use with a variety of head bolts and nuts including DIN933 metric hexagon head bolts and nuts in M5, M6 and M8 thread sizes. Inch thread sizes are also available. HexLock tooling is an inverted spring-loaded triple lance and form tool system. It is available as part of Mate's Ultraform tooling line for thick turret machines in one-inch to quarter-inch B stations. It is also available as part of Mate's other tooling lines by special order.
It has wear-resistant steel cutting edges for extended service life, a steel spring upper and lower stripper mechanism, and interchangeable replacement parts.
