Threaded at 1\/4-28 UNF with an overall length of 1.5 inches, this screw uses a hex-drive configuration with a 3\/8-inch width across flats and a 3\/16-inch hex height. Constructed from steel with a black oxide finish, it resists corrosion while maintaining dimensional accuracy under repeated use. Machinists, toolmakers, and fixture builders use this type of locating screw when repeatable part positioning is required on jigs, fixtures, and workholding devices.\u003c\/p\u003e\u003cp\u003eThis adjustable locating screw is suited for light industrial and precision machining environments where fine-thread adjustment and positive part contact are needed. The 1\/4-28 fine thread provides accurate depth control with minimal backlash, making it appropriate for fixture plates, drill jigs, and similar tooling components. It is packaged and sold individually, making it a practical replacement or addition to existing fixture assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for precise depth adjustment with minimal backlash\u003c\/li\u003e\n\u003cli\u003e1.5-inch overall length suitable for standard fixture plate depths\u003c\/li\u003e\n\u003cli\u003e3\/8-inch width across flats for wrench-driven installation and adjustment\u003c\/li\u003e\n\u003cli\u003eSteel construction provides strength and durability in tooling applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish adds corrosion resistance without significant dimensional change\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit adjustable locating screw for jigs, fixtures, drill plates, and workholding assemblies using 1\/4-28 UNF threaded locating screw positions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolmakers using a standard hex wrench sized for a 3\/8-inch width across flats. Thread the screw into the fixture body and adjust to the required depth before locking in place according to the fixture design. Ensure the mating threads in the fixture plate are clean and free of debris before installation to avoid galling the steel threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Height\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HJS-580-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51701659271474,"sku":"HJS-580-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7e827707fbe68f65bfe4e76230496e9.jpg?v=1788403291","url":"https:\/\/voomisupply.com\/products\/gibraltar-hjs-580-g-adjustable-locating-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
