Featuring a 1\/4-28 thread size with a 1 inch thread length and a steel body, this plunger delivers reliable spring-loaded engagement in demanding environments. The unit provides an initial end force of 1 pound and a final end force of 4 pounds, with a maximum plunger diameter of 0.118 inches and a projection of 3\/16 inches. A built-in locking element secures the plunger in position once installed, preventing back-out under vibration or repeated cycling. Machinists, tool and die technicians, and mechanical assembly professionals are the typical installers.\u003c\/p\u003e\u003cp\u003eThis spring plunger is suited for use in jigs, fixtures, machine tool components, and industrial equipment where repeatable, spring-loaded detent or stop action is required. The standard-length plunger profile fits conventional through-hole and blind-hole threaded applications. The 1\/4-28 fine thread provides precise installation torque control and is commonly used in precision mechanical assemblies where coarse threads are not appropriate. The steel nose and steel body construction make this plunger suitable for moderate-duty cycle environments where durability and dimensional consistency are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 fine thread with 1 inch thread length for standard installation depth\u003c\/li\u003e\n\u003cli\u003eSteel body and steel nose material for durability in mechanical assembly applications\u003c\/li\u003e\n\u003cli\u003eInitial end force of 1 pound and final end force of 4 pounds for controlled spring engagement\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.118 inches with 3\/16 inch projection\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element prevents back-out under vibration or repeated use\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type for straightforward fitment in common threaded bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard threaded spring plunger for use in mechanical fixtures, jigs, and machine tool assemblies requiring a 1\/4-28 threaded bore and a spring-loaded detent or stop function.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or mechanical assembly technicians using the appropriate thread-engagement tool for 1\/4-28 fine threads. Ensure the mating threaded bore is clean and free of debris before installation. Engage the locking element fully to prevent the plunger from backing out during operation. Do not exceed the recommended installation torque for the thread size and body material as specified by the applicable mechanical assembly standard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 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: 4 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\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SW10-4YA-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691123605810,"sku":"SW10-4YA-PT-G","price":46.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/880bbbb01e57dbf63817cc184310c8e2.jpg?v=1788280574","url":"https:\/\/voomisupply.com\/products\/gibraltar-sw10-4ya-pt-g-threaded-spring-plunger-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
