The 1\/4-20 UNC thread pattern is a widely used standard size, making this screw compatible with a broad range of tapped holes in enclosures, brackets, and equipment covers. Machined from aluminum and left uncoated, it offers a lightweight, corrosion-resistant option where steel fasteners are unnecessary. The knurled head provides a reliable grip surface for hand tightening without tools. With a 1 inch overall length and 3\/4 inch thread length, it suits standard panel thicknesses commonly found in electrical, HVAC, and mechanical enclosures.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw is suited for use in residential and commercial settings where repeated access to panels, covers, or equipment doors is required. Electricians, HVAC technicians, and mechanical assembly personnel use this type of fastener in control panels, equipment enclosures, junction boxes, and instrumentation housings. The without-shoulder design allows it to thread fully into tapped components without a standoff. Applications include securing removable covers on air handlers, electrical enclosures, and control cabinets where tool-free service access is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for broad compatibility with common tapped holes\u003c\/li\u003e\n  \u003cli\u003eKnurled head allows tool-free hand tightening and loosening\u003c\/li\u003e\n  \u003cli\u003eAluminum construction provides a lightweight, corrosion-resistant fastener\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for interior and protected enclosure use\u003c\/li\u003e\n  \u003cli\u003eWithout-shoulder design for full thread engagement into tapped components\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-A-225A Comp 2 and T-3 material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC aluminum thumb screw for use in any application with a corresponding tapped hole accepting a 1\/4-20 thread.

Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading the aluminum fastener. De-energize or lock out any electrical or mechanical equipment before servicing panels secured by these screws, in accordance with applicable NFPA 70 or facility lockout-tagout procedures. Do not apply power tools to the knurled head, as aluminum threads can strip under excessive torque.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: Without Shoulder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: QQ-A-225A Comp 2, T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.93 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: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: THS3056M04F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739268907314,"sku":"THS3056M04F16","price":19.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089603be8ed25c382e5b06b448da7164_416cce52-e7f8-4a5d-8e37-baf8eafbdb99.jpg?v=1788812455","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ths3056m04f16-thumb-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
