The SCBJ™ is a tool-only, non-spring captive panel screw designed for insertion into thin sheet materials, providing a threaded insert without a spring mechanism. It is available in unified thread sizes including #6-32 (632), with a recommended tightening torque of 9 in-lbs. Installation and pushout forces are specified for 5052-H34 aluminum and cold-rolled steel, with tensile strength of 2000 lbs and pushout forces of 175 lbs in aluminum and 3500 lbs in steel. The fastener requires proper installation to ensure full seating and performance.
