"No-Mar" Set Screws

PIC Design’s “No-Mar" Set Screws are self-locking as the expanding nylon insert compresses against a shaft and into the thread of the holding member.  Parts may be assembled or disassembled numerous times without damage to the shaft. "No-Mar" Set Screws afford secure full force contact regardless of shape of the shaft and will not scratch, mar, or deform the opposing surface.

Available in Socket (Class 3A) and Slotted (Class 2A) Head types in both inch and metric sizes.
