It features a 12-point box end with a 15-degree offset head angle, giving technicians the clearance needed to drive fasteners in tight or obstructed spaces. The open end and box end are machined from steel with a corrosion-resistant finish. Overall length is 11-13\/32 inches, and the wrench weighs 0.61 pounds. It is tether capable, making it suitable for work at height or in environments where dropped-tool protocols are enforced.\u003c\/p\u003e\u003cp\u003eThis wrench is used across mechanical, electrical, and industrial maintenance trades wherever metric fasteners are standard. The 15-degree offset is a common configuration for engine compartment work, structural assembly, and equipment maintenance where a flat wrench cannot reach. The tether-capable design makes it appropriate for elevated work platforms, tower maintenance, and confined-space jobs governed by dropped-object prevention programs. It is not rated as non-sparking and is not magnetic or ratcheting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 mm head size fits standard metric fasteners\u003c\/li\u003e\n\u003cli\u003e12-point box end for multiple engagement positions per revolution\u003c\/li\u003e\n\u003cli\u003e15-degree offset head angle improves clearance in confined spaces\u003c\/li\u003e\n\u003cli\u003eTether capable for compliance with dropped-object prevention programs\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant steel construction for long service life\u003c\/li\u003e\n\u003cli\u003eMeets GGG-W-636E federal specification standard\u003c\/li\u003e\n\u003cli\u003eLifetime warranty from the manufacturer\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 across general mechanical, industrial, and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is a hand tool used by mechanics, millwrights, electricians, and general maintenance technicians. Always ensure the wrench is fully seated on the fastener before applying torque to prevent rounding. When using in tethered applications, attach an approved lanyard through the tether point before beginning work. Inspect 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\u003eNumber of Points\u003c\/strong\u003e: 12\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\u003eHead Thickness\u003c\/strong\u003e: 1\/2 inch\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\u003eWeight\u003c\/strong\u003e: 0.61 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\u003eNon-Sparking\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\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: GGG-W-636E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 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: J1220MBASD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540847100210,"sku":"J1220MBASD","price":43.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0288d19293f13d9544f74622057a32ef.jpg?v=1785864900","url":"https:\/\/voomisupply.com\/products\/proto-j1220mbasd-combination-wrench-20-mm-15-degree-offset","provider":"Voomi Supply","version":"1.0","type":"link"}
