Built from Grade C-1045 steel to a strength grade of 5, it features a 1\/2-13 UNC thread with a Class 3 thread fit for precise engagement. The bolt measures 3 inches under the head with a 1-1\/2 inch thread length, making it suited to moderate clamping depth requirements. The T-slot head measures 7\/8 inches wide and 9\/32 inches tall, dimensioned to slide into standard 1\/2 inch T-slots. Licensed machinists, toolmakers, and maintenance technicians are the typical installers of this hardware.\u003c\/p\u003e\u003cp\u003eThis bolt is used in T-slot table fixtures, mill tables, jig plates, and similar workholding setups where a sliding, positionable fastener is required. The 1\/2 inch slot width fits standard 1\/2 inch T-slot channels commonly found on milling machine tables and fixture plates. It is sold individually, making it practical for replacement of a single worn or damaged fastener without committing to a bulk purchase. The uncoated finish is suited for dry or lightly lubricated indoor environments where corrosion is not a primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade C-1045 steel construction with Grade 5 strength rating for reliable clamping force\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread with Class 3 fit for precise, controlled engagement\u003c\/li\u003e\n\u003cli\u003e3 inches length under head accommodates moderate fixture stack heights\u003c\/li\u003e\n\u003cli\u003eT-slot head sized at 7\/8 inches wide and 9\/32 inches tall for standard 1\/2 inch slot channels\u003c\/li\u003e\n\u003cli\u003eUncoated finish provides a clean, bare-steel surface suitable for indoor fixturing use\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for straightforward single-fastener replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2 inch T-slot tracks on milling machine tables, fixture plates, and jig systems that accept 1\/2-13 UNC T-slot bolts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or maintenance technician. Slide the T-slot head into the track from the open end before positioning the workpiece, as the head cannot be inserted mid-slot. Use appropriately rated T-nuts, clamps, and clamping hardware rated for the application load. Inspect threads and the T-slot channel for burrs or damage before installation to ensure proper seating and clamping integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: Class 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Width\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.281 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: Grade 5, C-1045\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 20018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694235943218,"sku":"20018","price":15.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cc7c98574fcc038a8593bfe61ef69fa.jpg?v=1788322002","url":"https:\/\/voomisupply.com\/products\/value-collection-20018-t-slot-bolt-1-2-13-uncoated-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
