It features a 20 mm head size with a 15-degree offset angle, giving technicians the clearance needed to work in tight or obstructed spaces. The wrench is constructed from steel with a satin finish and measures 11-13\/32 inches overall in length. It meets ASME B107.100 standards and is corrosion-resistant, making it a reliable hand tool for demanding job sites. The tether-capable design supports tool-tethering safety programs used in elevated work areas and controlled environments.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for mechanical technicians, millwrights, pipefitters, and maintenance professionals working on industrial equipment, heavy machinery, and structural fasteners requiring metric sizing. The 20 mm head fits standard metric fasteners commonly found in commercial HVAC equipment, pumps, compressors, and general mechanical assemblies. The straight handle and 15-degree offset head improve access in recessed or flanged applications where a flat wrench cannot seat properly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 mm head size for metric fastener applications\u003c\/li\u003e\n\u003cli\u003e15-degree offset angle improves clearance in confined spaces\u003c\/li\u003e\n\u003cli\u003e12-point box end for greater contact and reduced fastener rounding\u003c\/li\u003e\n\u003cli\u003eSatin finish reduces glare and provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTether-capable design supports drop-prevention safety programs\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.100 standard for combination wrenches\u003c\/li\u003e\n\u003cli\u003eLimited 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 20 mm fasteners in industrial, mechanical, and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUse by qualified mechanical or maintenance technicians following applicable site safety protocols. Ensure the wrench is fully seated on the fastener before applying torque to prevent slippage and fastener damage. When working at height or over open equipment, attach the wrench to an approved tether anchor point using a compatible tethering system. Inspect the wrench for cracks or deformation before each use and remove from service if damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 20 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\u003eOpening Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11-13\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1\/2 inch\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: Satin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Straight\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\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.61 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited Lifetime\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: J1220MASD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51538288214322,"sku":"J1220MASD","price":48.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b63035df7d63d896c30b09b30dde5d4.jpg?v=1785821923","url":"https:\/\/voomisupply.com\/products\/proto-j1220masd-combination-wrench-20-mm-satin-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
