A press fit ensures that the pin will remain embedded in the base material unless removed.

Press fit pins sheet metal.

We are now in our fourth generation of providing the best product and great service. If you must use two press fit pins be certain to use gd t tolerancing with the first hole as the datum for the second hole to minimize error between the two features. Top reasons to choose us. A spiral groove cut into these pins relieves trapped air but stays in 360 contact with the hole for a secure fit that s easy to insert in and remove from blind holes.

Mike brieschke vice president of sales at aries engineering says a 0 25 inch diameter metal dowel that is press fit into a mild steel hole usually has an interference of 0 0015 inch. To remove thread a screw or tool into the tapped hole then pull the pin out. Parts in noncritical assemblies tend to have looser tolerances. Second rule of press fits.

Never more than two pins per assembly operation. Family owned for 98 years. Pemsert self clinching flush nuts are designed to be completely flush in sheets as thin as 060 1 5mm. The benefits of self location aren t just for welded or sheet metal parts.

The clinch design provides high strength in sheets as thin as 031 0 8 mm. Pinpoints a fastener s resistance to being pulled through the metal sheet when applying a clamping torque. We generally recommend the below tolerances when inserting a pin. We engineer manufacture press brake dies to fit your needs.

With a press installation is relatively simple. Even better use only one interference fit and align the parts with a slip fit second pin. Concealed head standoffs types csos css. Standoffs for sheet metal.

The thfe is recommended for use in steel or aluminum sheets hrb rockwell b scale 85 or less and hb hardness brinell 165 or less.

This feature allows the side of the sheet opposite installation to remain smooth and untouched. A slip fit allows objects to be easily removed from the designated hole but ensures a firm fit.
