Increased production rates from fastener press
The mid-range Pemserter Tech2t automatic press for installing self-clinching fasteners offers increased production rates and improved insertion quality
Only mating hardware is required to complete final component attachment.
Their unique design features include an integrated nylon (nonmetallic) locking element to prevent loosening of mating threaded hardware; a broaching knurl to create a firm, interference-type fit resistant to rotation; and a shoulder to act as a positive stop during the installation process.
PEM (Type CFN) locknuts install in sheets as thin as 0.91mm and are available in thread sizes 4-40 and M3.
They install easily by inserting the fastener into mounting anvil hole, placing the mounting hole over the shank of the fastener, and (with punch and anvil surfaces parallel) applying enough squeezing force until the shoulder of the fastener contacts the sheet.
CAD drawings (in most formats) for these fasteners are available free of charge from the company's website.
