It features a 3\/8-16 threaded shank with a 0.75-inch thread length and a knurled locking knob that allows the plunger to be manually retracted and locked in the retracted position. The plunger diameter ranges from 0.185 to 0.186 inches, with an initial end force of 0.5 pounds and a final end force of 3 pounds. Constructed from stainless steel, this plunger is suited for environments requiring corrosion resistance. Machinists, millwrights, and mechanical technicians typically install these components during machine setup or equipment assembly.\u003c\/p\u003e\u003cp\u003eThe SKLS-3-PT-G is used in jigs, fixtures, tooling plates, and light machinery where repeatable positioning or detent locking is required. The locking knob mechanism allows the plunger to be held in the retracted position, freeing both hands during part loading or changeover. This makes it well suited for production fixtures, assembly workholding, and adjustable mechanical stops in both light industrial and precision equipment applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking knob retracts and holds plunger in the retracted position for hands-free operation\u003c\/li\u003e\n\u003cli\u003eKnurled knob provides positive grip for tool-free manual actuation\u003c\/li\u003e\n\u003cli\u003eStainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread for easy installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eInitial end force of 0.5 pounds rising to a final end force of 3 pounds for reliable detent action\u003c\/li\u003e\n\u003cli\u003eCompact plunger projection of 0.22 inches suits tight clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 threaded locking plunger suitable for use in jigs, fixtures, tooling plates, and mechanical assemblies requiring a retained locking spring plunger with a knurled knob handle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger shank into a tapped 3\/8-16 hole in the workpiece or fixture plate. Ensure the mating hole is clean and threaded to the correct depth to accommodate the 0.75-inch thread length. A wrench flat or the knurled knob may be used to achieve proper seating torque per the equipment manufacturer's fixture specifications. Retract and lock the plunger before inserting or removing any component that contacts the plunger tip to avoid damage to the plunger or the mating part.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SKLS-3-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695120417074,"sku":"SKLS-3-PT-G","price":28.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e5f42f8108b7db9f52db5e85f214f34.jpg?v=1788331499","url":"https:\/\/voomisupply.com\/products\/gibraltar-skls-3-pt-g-locking-knob-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
