It carries a 4-40 UNC thread and measures 0.6875 inches in overall length. The knurled head diameter is 0.375 inches with a head height of 0.1875 inches, giving a low-profile grip. The shoulder diameter is 0.312 inches with a shoulder length of 0.125 inches. Supplied uncoated, the 303 stainless steel construction resists corrosion in light-duty wet or chemically active environments. Electricians, panel builders, and mechanical technicians use these fasteners to secure covers, access panels, and instrumentation enclosures where frequent removal is required.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw fits standard 4-40 UNC threaded inserts and tapped holes found across electrical enclosures, instrumentation panels, HVAC control boxes, and light mechanical assemblies. The with-shoulder design locates components accurately against a mating surface, making it a common choice in control panel fabrication and field-service applications where repeated hand removal is expected. The uncoated 303 stainless finish is appropriate for indoor environments and moderate-exposure installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e303 stainless steel body with uncoated finish for corrosion resistance in light-duty service\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard for compatibility with common tapped holes and inserts\u003c\/li\u003e\n  \u003cli\u003eKnurled head allows secure hand-tightening without tools\u003c\/li\u003e\n  \u003cli\u003eWith-shoulder design provides accurate component location against mating surfaces\u003c\/li\u003e\n  \u003cli\u003eCompact 0.6875-inch overall length suits shallow panel and enclosure applications\u003c\/li\u003e\n  \u003cli\u003eMeets multiple material and finish standards including ASTM B633 and QQ-S-763\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application with a standard 4-40 UNC tapped hole or threaded insert where a hand-adjustable, shoulder-style thumb screw is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — hand-tighten only to the torque appropriate for the mating material and application. Ensure the mating thread is clean and free of debris before installation to avoid galling, which 303 stainless steel can be susceptible to under high friction. Power down or de-energize any enclosure before removing or installing fasteners on live electrical panels, following applicable NEC requirements. Do not use power drivers on this fastener type.\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\u003eHead Type\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: With Shoulder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 303 Stainless Steel\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: Uncoated\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.19 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: THS1003M07F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51738788135218,"sku":"THS1003M07F16","price":22.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e65a26e1d14e7b8fa8ae0cd4148ddfca_35610188-8231-416a-88db-d9b9c4e3546e.jpg?v=1788804485","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ths1003m07f16-thumb-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
