The wrench features a 15-degree offset head angle on a straight handle, allowing clearance over fasteners in confined work areas. Constructed from steel with a polished finish, it measures 14-7\/8 inches overall length and weighs 1.33 pounds. The tether-capable design supports use in elevated work environments or any application where tool retention is required for safety compliance. It meets ASME B107.100-2010 standards and carries a lifetime warranty.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for heavy equipment maintenance, industrial assembly, and mechanical service work in both shop and field environments. The 28 mm head size fits metric fasteners common on commercial vehicles, heavy machinery, and industrial equipment. The 15-degree offset provides knuckle clearance and improved torque angle in tight access points. It is appropriate for any trade professional requiring a reliable, full-size metric combination wrench for regular service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e28 mm head size for metric fastener applications\u003c\/li\u003e\n\u003cli\u003e15-degree offset head angle improves clearance in confined spaces\u003c\/li\u003e\n\u003cli\u003eTether-capable design supports use in elevated or drop-hazard environments\u003c\/li\u003e\n\u003cli\u003eSteel construction with polished, corrosion-resistant finish\u003c\/li\u003e\n\u003cli\u003e12-point box end for increased contact with fastener flats\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.100-2010 standard\u003c\/li\u003e\n\u003cli\u003eBacked by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric combination wrench for use with 28 mm fasteners across industrial, mechanical, and heavy equipment service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is intended for use by qualified mechanics and maintenance technicians. Always confirm fastener size before applying torque to avoid rounding. When used in elevated or overhead environments, attach the tether anchor point to an appropriate lanyard or tool tethering system per applicable worksite fall-protection protocols. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 28 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Offset Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Straight\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: Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Tether Capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Sparking\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.8 inches L x 2.3 inches W x 0.9 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.100-2010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J1228M-T500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51539054854450,"sku":"J1228M-T500","price":81.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18110e18032fa3ec4feb86c7eea2393f_52bf2c6f-0c7b-4286-ad30-122065dc2a6e.jpg?v=1785833896","url":"https:\/\/voomisupply.com\/products\/proto-j1228m-t500-combination-wrench-28-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
