It uses a 1\/4-20 thread and delivers an initial end force of 1 pound, rising to a final end force of 3.5 pounds at full compression. The steel body and steel nose provide durability in industrial and trade environments. At 0.531 inches in thread length and a maximum plunger diameter of 0.119 inches, this is a compact, precise component suited for tight-tolerance installations. A built-in locking element prevents the plunger from backing out under vibration or repeated cycling, making it reliable in demanding service conditions.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in mechanical fixtures, jigs, tooling plates, and equipment panels where a repeatable spring-loaded detent or stop is required. The stubby plunger length and small projection of 0.078 inches make it well suited for shallow-depth applications where standard-length plungers would conflict with adjacent components. Machinists, maintenance technicians, and equipment assemblers commonly install this type of component during fabrication or field service of industrial machinery and trade equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread for straightforward installation in tapped holes\u003c\/li\u003e\n  \u003cli\u003eStubby plunger profile with 0.531 inch thread length fits shallow assemblies\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1 pound and final end force of 3.5 pounds for light-duty detent applications\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose construction for durability in industrial use\u003c\/li\u003e\n  \u003cli\u003eLocking element prevents backing out under vibration or repeated loading cycles\u003c\/li\u003e\n  \u003cli\u003eLow-profile 0.078 inch plunger projection minimizes interference with adjacent parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard threaded spring plunger for use in any tapped 1\/4-20 hole requiring a spring-loaded indexing or detent function in mechanical assemblies and industrial fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly tapped 1\/4-20 hole to the correct depth to achieve full thread engagement. Use an appropriate driver or hex key on the locking element to seat the plunger and prevent rotation once positioned. Ensure the assembly is de-energized and depressurized before servicing any equipment that houses this component. Do not overtighten, as this can deform the plunger body and affect spring performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.119 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SW10-4SL-PT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":67647512576306,"sku":"SW10-4SL-PT","price":28.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0953cd2b2abbf84e9d2710d4a8ccb68.jpg?v=1790459784","url":"https:\/\/voomisupply.com\/products\/gibraltar-sw10-4sl-pt-threaded-spring-plunger-1-4-20-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
