It features a 1.875-inch diameter sphere with a smooth grip surface and a 1\/2-20 threaded bore machined to a 0.75-inch hole depth. The natural stainless steel finish provides corrosion resistance without coating or plating. This type of knob is commonly installed by machinists, millwrights, and equipment maintenance technicians where a firm, hand-operable control point is needed on jigs, fixtures, clamps, or adjustable machinery components.\u003c\/p\u003e\n\u003cp\u003eThe SSBK-053-G suits light-duty to medium-duty equipment panels, enclosures, and fixtures requiring a durable, corrosion-resistant knob. The 1\/2-20 fine thread is commonly found on precision adjustment hardware, tooling, and machine frames. The smooth grip profile keeps the profile clean and snag-free in environments where gloves or debris contact is a concern. Typical applications include manufacturing equipment, HVAC equipment access panels, pump housings, and any threaded stud or bolt requiring a hand-tightened knob.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 threaded hole with 0.75-inch hole depth for secure engagement\u003c\/li\u003e\n  \u003cli\u003e1.875-inch diameter provides adequate grip surface for hand tightening\u003c\/li\u003e\n  \u003cli\u003eSmooth grip profile reduces snag risk and simplifies cleaning\u003c\/li\u003e\n  \u003cli\u003eNatural finish — no coating to chip, peel, or degrade over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or aftermarket replacement ball knob for any threaded stud or bolt with a 1\/2-20 thread specification on machinery, fixtures, or equipment panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the knob onto a compatible 1\/2-20 stud or bolt by hand. Ensure the mating thread is clean and free of debris before installation to prevent cross-threading. Do not use impact tools or excessive torque, as ball knobs are intended for hand operation. Power down or de-energize any equipment before accessing panels or components where this knob will be installed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrip Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Natural\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.84 pounds\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: SSBK-053-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711294210354,"sku":"SSBK-053-G","price":30.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/745ff47f7472061a133a5a99e55ea7a0.jpg?v=1788475399","url":"https:\/\/voomisupply.com\/products\/gibraltar-ssbk-053-g-ball-knob-threaded-hole-1-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
