It features a 7\/8-9 UNC thread with a 4-inch thread length and fits a 1-inch slot width. The bolt is manufactured from C-1045 steel, providing solid mechanical strength for clamping applications under significant load. With a 20-inch length under the head, this fastener is suited for deep-reach setups where standard-length T-bolts fall short. The uncoated finish leaves the steel bare for applications where coating thickness or surface treatment compatibility is a consideration.\u003c\/p\u003e\u003cp\u003eThis T-slot bolt is used in industrial and machining environments, including milling machine tables, drill press tables, welding fixtures, and modular aluminum or steel framing assemblies. It is installed by machinists, toolmakers, millwrights, and maintenance technicians wherever secure, adjustable clamping in a T-slot channel is required. The 1-3\/4-inch head width and 5\/8-inch head height are sized to engage standard 1-inch T-slot channels without rocking or pull-through under clamping force.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread with Class 3 fit for tight, precise thread engagement\u003c\/li\u003e\n\u003cli\u003e4-inch thread length provides ample engagement for standard and deep clamping nuts\u003c\/li\u003e\n\u003cli\u003e20-inch length under head accommodates deep T-slot fixture setups\u003c\/li\u003e\n\u003cli\u003e1-inch slot width fits standard machine table T-slots\u003c\/li\u003e\n\u003cli\u003eC-1045 steel construction for high tensile strength in clamping applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish for compatibility with surface-sensitive fixture requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-profile T-slot bolt for use in 1-inch T-slot channels on machine tables, fixture plates, and modular framing systems with 7\/8-9 UNC clamping hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eT-slot bolts are typically installed and adjusted by machinists or maintenance technicians using standard wrenches or socket sets. Always confirm the slot width of the receiving channel matches the 1-inch head profile before insertion to prevent binding or damage. Ensure the machine table or fixture frame is de-energized and stationary before installing or repositioning clamping hardware. Do not overtighten beyond the torque capacity of the C-1045 material grade or the clamping nut being used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: Class 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Width\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/8 inch\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: C-1045\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 4.5 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70033\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696051487026,"sku":"70033","price":81.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e08090256d4e76dde339f6d2bbb64e3.jpg?v=1788339930","url":"https:\/\/voomisupply.com\/products\/value-collection-70033-steel-t-slot-bolt-7-8-9-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
