It features an M4 x 0.7 thread with a 13 mm thread length and a maximum plunger diameter of 1.78 mm. The plunger projects 2.5 mm and delivers an initial end force of 0.23 kg rising to a final end force of 0.91 kg, making it suited for applications requiring repeatable, low-force ball or pin detent action. Both the body and nose are steel construction with a black finish. A locking element is included to secure the plunger in position after installation. Machinists, toolmakers, and fixture builders are the typical installers.\u003c\/p\u003e\u003cp\u003eThis spring plunger is used in jigs, fixtures, machine tool components, and precision assemblies where a compact M4-threaded detent point is needed. The short body length of 13 mm suits confined mounting spaces in tooling plates, workholding fixtures, and light mechanical assemblies. The locking element allows the installer to lock the plunger at the desired engagement depth once the correct force setting is dialed in.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM4 x 0.7 thread with 13 mm thread length fits standard metric tapped holes\u003c\/li\u003e\n\u003cli\u003eShort plunger length type for compact or space-restricted fixture applications\u003c\/li\u003e\n\u003cli\u003eSteel body and nose construction for durability in tooling environments\u003c\/li\u003e\n\u003cli\u003eBlack finish for corrosion resistance and identification\u003c\/li\u003e\n\u003cli\u003eLocking element included to fix plunger depth after adjustment\u003c\/li\u003e\n\u003cli\u003eLow end-force range (0.23 kg initial to 0.91 kg final) suits light detent and indexing duties\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for metric-threaded jigs, fixtures, and tooling assemblies requiring an M4 x 0.7 short-body spring plunger with a locking element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped M4 x 0.7 through or blind hole with sufficient depth to accept the 13 mm thread length. Use the appropriate hex key or spanner to thread the plunger in and engage the locking element once the desired projection depth is set. Ensure the mating assembly is de-energized or secured before adjusting plunger position in active tooling. Do not exceed the rated end force range by over-compressing the plunger nose during assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4 x 0.7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 1.78 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 2.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.23 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 0.91 kg\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\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JERGENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52105728000306,"sku":"27170","price":17.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d366ec19f8b4127b5aebdc083dfb839.jpg?v=1790072892","url":"https:\/\/voomisupply.com\/products\/jergens-27170-threaded-spring-plunger-m4-x-0-7","provider":"Voomi Supply","version":"1.0","type":"link"}
