Thru-hole Threaded Standoffs – Types SO, SOA, SOS

The PEM RT® free-running locking feature allows the mating screw to turn freely until clamp load is applied. If the tightening force is removed, these standoffs no longer provide any torsional resistance to rotation until clamp load is reapplied.

• Improves load distribution among all threads, reducing stress on first engaged thread. • Turns freely until clamp load is applied. • Resistant to vibrational loosening. • Locking feature reusability is not affected by number of on/off cycles. • Uses same mounting hole and installation tooling as standard standoff.
