PEM self-clinching blind fasteners are used in applications requiring closed thread ends. B SELF-CLINCHING BLIND FASTENERSSELF-CLINCHING BLIND FASTENERS PEM brand self-clinching blind fasteners provide permanently mounted blind threads in metal sheets as thin as .040/1 mm. Provides barrier to protect threads against foreign matter. Limits screw penetration, protecting internal components from potential damage. Available on special order with free-running locking thread feature. PEM blind fasteners employ the proven PEM self-clinching design and are easily installed into properly sized holes. Shanks of PEM fasteners act as their own pilots. PEM blind fasteners can be installed with any standard press applying squeezing forces between parallel surfaces. PEM self-clinching blind fasteners are available in thread sizes from 4-40 through 1/4-20 / M3 through M6 in carbon or stainless steel.
