The plunger body is machined steel with a 3\/8-16 thread size and a thread length of 1-1\/8 inches. The plunger nose is also steel, with a minimum diameter of 0.186 inches and a maximum diameter of 0.187 inches. It delivers an initial end force of 5.5 pounds and a final end force of 14.5 pounds, with a projection of 3\/16 inches. This part is installed by machinists, toolmakers, and mechanical assemblers working with fixtures, jigs, and precision assemblies.\u003c\/p\u003e\n\u003cp\u003eThe S58 is suited for use in industrial and manufacturing environments where a reliable spring-loaded plunger is needed for part registration, detent positioning, or light-duty locking without a dedicated locking element. The standard plunger length type makes it appropriate for general-purpose threaded bore installations in metal fixtures, machine components, and assembly tooling where repeatable spring force is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 thread size with 1-1\/8 inch thread length for broad fitment in standard tapped bores\u003c\/li\u003e\n  \u003cli\u003e5.5 lb initial end force and 14.5 lb final end force for light-to-moderate positioning duty\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter range of 0.186 to 0.187 inches for consistent, precise engagement\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection suits shallow-detent and registration applications\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  straightforward installation and removal without secondary retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style threaded spring plunger for use in any application requiring a 3\/8-16 threaded bore with a 1-1\/8 inch body length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a hex key or spanner wrench appropriate for the plunger body style  -  do not overtighten, as this can restrict plunger travel or damage the spring. Thread the plunger into a clean, properly tapped 3\/8-16 bore and verify full, unobstructed plunger projection before final assembly.
