The plunger features a 5\/8-11 external thread with a 1 inch thread length and a knobless threaded stud configuration, meaning it is operated by an externally applied knob or handle rather than an integrated grip. The spring mechanism delivers 5 pounds of initial end force and 10 pounds of final end force, providing consistent, repeatable engagement. Built from steel with a zinc finish, this plunger is suited for environments where moderate corrosion resistance and structural durability are required.\u003c\/p\u003e\n\u003cp\u003eThe GIBRALTAR 34151 is used in jig and fixture assemblies, machine guarding, tooling plates, and general industrial equipment where a spring-loaded locating or holding point is needed. The threaded stud body allows direct installation into tapped holes or mounting brackets. The 0.311 inch maximum plunger diameter and 5\/16 inch plunger projection make it appropriate for compact assemblies with limited clearance. The locking element confirms the unit stays seated under operational vibration or load conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking plunger type with locking element for secure seating under vibration\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 external thread with 1 inch thread length for direct installation into tapped holes\u003c\/li\u003e\n  \u003cli\u003eKnobless threaded stud configuration accommodates external operator hardware\u003c\/li\u003e\n  \u003cli\u003eSpring force range of 5 pounds initial to 10 pounds final end force\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for durability and moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCompact 0.311 inch maximum plunger diameter suits tight-clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for industrial jig, fixture, and positioning assemblies requiring a 5\/8-11 threaded spring plunger with a knobless stud body.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the stud body into a pre-tapped 5\/8-11 hole in the host assembly. Ensure the mating thread depth accommodates the full 1 inch thread length before installation. Disengage any spring load from the plunger tip before threading to avoid cross-threading. A wrench flat or jam nut may be used to lock the body at the desired depth once positioned.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Thread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Threaded Stud (without Knob)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.311 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 2.186 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: +0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/16 inches\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 34151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691434737970,"sku":"34151","price":46.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ffcf2c850f33e09be54743448b74e6b_2c44a62b-f650-4b7f-93a7-0f3b8c1fa052.jpg?v=1788284988","url":"https:\/\/voomisupply.com\/products\/gibraltar-34151-knob-handle-plunger-5-8-11-steel-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
