Manufactured without a shoulder, this fastener has an overall length of 1-3\/8 inches, a head diameter of 3\/16 inches, and a head height of 3\/8 inches. The 18-8 stainless steel construction provides corrosion resistance suitable for indoor and light outdoor applications. It follows inch-measurement standards and is sold individually. Electricians, panel fabricators, HVAC technicians, and equipment assemblers commonly use this type of fastener when frequent access or adjustment is needed without tools.\u003c\/p\u003e\n\u003cp\u003eThis thumb screw is suited for light-duty fastening tasks in control panels, enclosures, junction boxes, and equipment covers. Its 4-40 UNC thread is a fine, small-diameter designation widely used in electrical and instrumentation assemblies. The knurled head allows finger-tightening in confined spaces where a screwdriver cannot be used. It is appropriate for both residential and commercial equipment assembly and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread for compatibility with standard small-diameter tapped holes\u003c\/li\u003e\n  \u003cli\u003eKnurled head design allows tool-free hand tightening and loosening\u003c\/li\u003e\n  \u003cli\u003eWithout-shoulder configuration for flush or recessed seating\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with overall length of 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003eIndividually packaged, sold as a single fastener\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or supplemental fastener for equipment assemblies requiring a 4-40 UNC thread thumb screw with a knurled head in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by hand; no special tools are required for tightening. Verify the mating thread in the receiving component is 4-40 UNC before installation to avoid cross-threading or thread damage. De-energize any electrical panel or enclosure before servicing fasteners on live equipment covers. Do not overtighten by hand or with tools, as small-diameter stainless fasteners are susceptible to galling.\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: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Z0736\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695932637490,"sku":"Z0736","price":15.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a7cfdd40bcc9beb3ba7bdf8d350b7b6.jpg?v=1788339530","url":"https:\/\/voomisupply.com\/products\/gibraltar-z0736-thumb-screw-4-40-knurled-head-18-8-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
