Designed for hand-tightening applications, this fastener allows tool-free assembly and disassembly in panels, enclosures, fixtures, and light-duty mechanical assemblies. The oval head provides a smooth, ergonomic gripping surface for repeated adjustment. With a head diameter of 0.55 inches and a head height of 0.64 inches, the fastener is compact enough for confined spaces while still offering adequate torque by hand. Overall length is 0.75 inches.

De-energize any electrical enclosure or panel before accessing interior components when replacing or installing thumb screws in those assemblies. Ensure the mating threaded hole or nut is clean and free of debris before threading in the fastener. Do not over-tighten by hand, as brass threads can be damaged by excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: Without Shoulder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R63283969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693117767986,"sku":"R63283969","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5e474ce2a02c895cbc4156b3834ddcf.jpg?v=1788307547","url":"https:\/\/voomisupply.com\/products\/value-collection-r63283969-brass-thumb-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
