The knurled head provides finger grip for quick installation and removal without a screwdriver. Made from brass with a zinc finish, this fastener resists corrosion in typical indoor environments. The overall length is 11\/16 inches, with a thread length of 1\/2 inch. Head diameter is 3\/8 inches and head height is 3\/16 inches. This is a shoulder-free design, meaning the thread runs consistent with no unthreaded shoulder section below the head.\u003c\/p\u003e\u003cp\u003eThis thumb screw is suited for use in electrical enclosures, instrument panels, HVAC equipment covers, control box assemblies, and similar light-duty applications where frequent access is required. The 8-32 UNC thread is a common size in electrical and electronic equipment, making this fastener a standard replacement or stock item for maintenance and service shops. It is sold individually and is appropriate for both trade and general assembly use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnurled head allows tool-free hand tightening and removal\u003c\/li\u003e\n\u003cli\u003e8-32 UNC thread is widely compatible with standard electrical and panel hardware\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc finish for corrosion resistance in indoor applications\u003c\/li\u003e\n\u003cli\u003eNo-shoulder design provides consistent threading from head to tip\u003c\/li\u003e\n\u003cli\u003e1\/2 inch thread length suits standard panel and cover thickness applications\u003c\/li\u003e\n\u003cli\u003eMeets multiple material and finish standards including ASTM B633\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-32 UNC thumb screw for use in electrical enclosures, HVAC equipment panels, instrument housings, and similar assemblies that require tool-free fastener access.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fastener is installed by hand and requires no tools under normal torque conditions. Before replacing thumb screws on live electrical enclosures or control panels, de-energize the equipment per applicable NEC guidelines. Inspect mating threads for damage before installation to avoid cross-threading the brass fastener, as brass is softer than steel and can strip under excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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\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: THS3025M01F21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744774226226,"sku":"THS3025M01F21","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089603be8ed25c382e5b06b448da7164_6a5bf1bc-c3dd-40e4-a977-ac941ac7266e.jpg?v=1788860365","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ths3025m01f21-brass-thumb-screw-8-32","provider":"Voomi Supply","version":"1.0","type":"link"}
