It features a 1\/4-20 thread size with a 1 inch thread length and a steel body finished in black. The plunger nose is made from Delrin, delivering smooth, low-friction contact against mating surfaces. A built-in locking element secures the plunger position after installation, preventing loosening from vibration. Initial end force is 3 pounds and final end force is 13 pounds, giving technicians and machinists a predictable spring load range for precise part retention and detent applications.\u003c\/p\u003e\u003cp\u003eThe 57088G is suited for use in machine tool fixtures, jigs, production equipment, and general industrial assemblies where repeatable spring-loaded positioning is required. The 1\/4-20 thread makes it compatible with standard tapped holes in steel, aluminum, and plastic housings. Its compact plunger diameter of 0.118 inches and 3\/16 inch projection keep the installed footprint minimal, making it practical in tight assemblies where space is limited. Professionals working in maintenance, fabrication, and fixture building will find this plunger a reliable off-the-shelf solution for detent and retention tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread with 1 inch thread length for standard tapped hole installation\u003c\/li\u003e\n\u003cli\u003eSteel body with black finish for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eDelrin nose material provides smooth, low-friction plunger contact\u003c\/li\u003e\n\u003cli\u003eLocking element prevents loosening under vibration\u003c\/li\u003e\n\u003cli\u003e3 pound initial end force and 13 pound final end force for predictable spring load\u003c\/li\u003e\n\u003cli\u003eCompact 0.118 inch plunger diameter and 3\/16 inch projection for tight-clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard threaded spring plunger for use in any application with a 1\/4-20 tapped hole requiring spring-loaded indexing or positioning.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 5\/64 inch hex key to thread the plunger body into the prepared 1\/4-20 tapped hole.
