It features a 5\/16 inch head diameter, 3\/16 inch head height, and an overall length of 9\/16 inch with a 3\/8 inch thread length. The uncoated 303 stainless steel construction provides corrosion resistance suitable for instrumentation, panel assembly, and light mechanical enclosures. This fastener is installed by hand without tools, making it well suited for access panels, covers, and components that require frequent removal. Electricians, HVAC technicians, and panel fabricators commonly use this style of thumb screw in low-load, tool-free fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw is designed for use in indoor and light-duty outdoor assemblies where finger-tightened fastening is required. It is commonly found in electrical enclosures, control panels, instrument housings, and HVAC equipment access covers. The 4-40 UNC thread is a standard size in light-gauge sheet metal and machined component applications. The knurled head provides a reliable grip for hand tightening without requiring a driver. No shoulder is present, making it appropriate for flush or near-flush panel mounting configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e303 stainless steel construction for corrosion resistance in light-duty environments\u003c\/li\u003e\n  \u003cli\u003eKnurled head design allows hand tightening without tools\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard for compatibility with common light-gauge panel and enclosure tapping\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch overall length with 3\/8 inch thread engagement length\u003c\/li\u003e\n  \u003cli\u003eWithout-shoulder configuration suits flush panel and cover fastening\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional tolerances and resists galling common with stainless fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for any assembly requiring a 4-40 UNC knurled head thumb screw without a shoulder.

De-energize all electrical panels and enclosures before servicing fasteners on live equipment, in accordance with NFPA 70E lockout\/tagout requirements. Avoid over-tightening stainless steel fasteners into tapped stainless or aluminum threads, as galling can occur. Verify thread engagement depth against the mating tapped hole to ensure full thread engagement without bottoming out.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\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: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/16 inches (0.1875 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: 303 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B633; QQ-A-225A Comp 2; QQ-B-626B Comp 22; QQ-N-290A; QQ-S-633; QQ-S-763; T-3; Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161516\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.29 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: THS3002M07F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51736992088370,"sku":"THS3002M07F16","price":22.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089603be8ed25c382e5b06b448da7164_78a48456-0dd8-405e-976f-811352094cac.jpg?v=1788782818","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ths3002m07f16-thumb-screw-4-40-303-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
