Manufactured to a 6-32 UNC thread standard with a zinc finish over Grade 2 steel, this fastener delivers corrosion resistance suitable for light industrial, electrical enclosure, and panel assembly use. The knurled head profile provides grip for finger-tightening, and the screw ships without a shoulder, making it a straightforward replacement or new-install fastener for standard 6-32 tapped holes. Licensed tradespeople and assembly technicians working on enclosures, control panels, and equipment access covers are the primary installers.\u003c\/p\u003e\u003cp\u003eThis thumb screw is suited for applications requiring frequent hand-access removal and reinstallation without tools, such as electrical control panel covers, HVAC equipment access panels, junction box lids, and light-duty mechanical assemblies. The 6-32 UNC thread is one of the most common fine-pitch machine screw threads found in electrical and electronic enclosures. The zinc finish meets ASTM B633 and QQ-S-633 Type 1 standards, providing a baseline level of corrosion protection for indoor and sheltered installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-32 UNC thread for compatibility with standard machine screw tapped holes\u003c\/li\u003e\n\u003cli\u003eKnurled head design allows secure finger-tightening without tools\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction with zinc finish meeting ASTM B633 and QQ-S-633 Type 1\u003c\/li\u003e\n\u003cli\u003eWithout-shoulder design for straightforward thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/8 inch thread length with 9\/16 inch overall length\u003c\/li\u003e\n\u003cli\u003e5\/16 inch head diameter with 3\/16 inch head height for low-profile clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation thumb screw for any application using 6-32 UNC tapped holes requiring hand-tightened fastening.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no tools given the knurled head design, but torque-sensitive applications should verify that finger-tight seating is sufficient for the assembly requirements. Always de-energize electrical panels and enclosures before removing or installing fasteners on live equipment covers, following applicable NEC guidelines. Verify that the mating tapped hole thread standard matches 6-32 UNC before installation to avoid cross-threading or thread damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\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: Knurled\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: 9\/16 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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B633, QQ-S-633, Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.29 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: THS3008M10F21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51738497548594,"sku":"THS3008M10F21","price":59.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089603be8ed25c382e5b06b448da7164_5636ef9c-ca81-46b0-b225-1b4763a739bd.jpg?v=1788800283","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ths3008m10f21-steel-thumb-screw-6-32","provider":"Voomi Supply","version":"1.0","type":"link"}
