Built with a stainless steel body and a Delrin swivel pad, it provides firm, non-marring contact on workpiece surfaces. The 1\/4-20 UNC thread runs 1-11\/32 inches in length with a 1.5-inch overall length. A 7.5-degree swivel angle allows the pad to self-align to angled or irregular surfaces, reducing point loading. The 0.185-inch pad diameter suits compact fixtures and tooling setups. Drive is via a 1\/8-inch hex key. This type of fastener is commonly installed by machinists, toolmakers, and mechanical assembly technicians.\u003c\/p\u003e\n\u003cp\u003eThe NSSC329 is suited for use in machine tooling, fixtures, jigs, and precision assemblies where controlled surface contact and minor angular adjustment are required. The stainless steel construction makes it appropriate for environments where corrosion resistance is a factor, such as food processing equipment, washdown areas, or humid industrial settings. The Delrin pad protects finished or sensitive surfaces from damage during clamping or leveling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel body with black oxide finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDelrin swivel pad for non-marring, self-aligning contact\u003c\/li\u003e\n  \u003cli\u003e7.5-degree swivel angle accommodates angled and uneven surfaces\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for standard tooling and fixture compatibility\u003c\/li\u003e\n  \u003cli\u003e0.185-inch pad diameter suited for compact fixture applications\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex key drive for precise torque application in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install swivel pad leveling screw for fixtures, jigs, and tooling assemblies using 1\/4-20 UNC threaded components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using a 1\/8-inch hex key. Ensure the mating threaded hole or nut is clean and free of debris before installation. Do not overtighten, as the Delrin swivel pad can deform under excessive clamp load. Verify swivel pad seating and surface contact alignment before locking the assembly into final position.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-11\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwivel Angle\u003c\/strong\u003e: 7.5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Material\u003c\/strong\u003e: Delrin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NSSC329\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972196827442,"sku":"NSSC329","price":44.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea850b01a70443e68190ef264444a933_6c2cb501-fc24-41f6-85a7-e5ace0f52200.jpg?v=1789964225","url":"https:\/\/voomisupply.com\/products\/vlier-nssc329-swivel-pad-leveling-screw-1-4-20-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
