The wrench combines a 12-point box end with an open end on a straight handle, allowing ratcheting action without removing and repositioning the tool on the fastener. Constructed from steel with a chrome finish for corrosion resistance, it measures 7.5 inches overall. The 0-degree head offset keeps the working plane flat against the fastener surface, and the 15-degree opening angle on the open end provides clearance in confined areas. It is tether-capable, making it suitable for elevated or overhead work where dropped-tool safety protocols apply.\u003c\/p\u003e\n\u003cp\u003eThis wrench is used across HVAC, plumbing, electrical, and general mechanical trade work wherever 9\/16-inch fasteners are encountered. The ratcheting box end is particularly useful during equipment installation, panel work, and mechanical assembly where swing arc is limited. The corrosion-resistant chrome finish holds up in field conditions including exposure to moisture and cleaning agents. At 0.22 pounds, it adds minimal weight to a tool pouch or belt kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRatcheting 12-point box end allows fastener driving without lifting off the nut or bolt head\u003c\/li\u003e\n  \u003cli\u003e0-degree head offset for flat, direct engagement in standard clearance situations\u003c\/li\u003e\n  \u003cli\u003e15-degree open-end opening angle for access in restricted spaces\u003c\/li\u003e\n  \u003cli\u003eTether-capable design supports compliance with dropped-object prevention programs\u003c\/li\u003e\n  \u003cli\u003eChrome finish provides corrosion resistance for extended field service life\u003c\/li\u003e\n  \u003cli\u003eMeets ASME standards for hand tool dimensional and performance requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 9\/16-inch combination wrench suitable for use with SAE fasteners across residential and commercial mechanical, HVAC, plumbing, and electrical trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is intended for use by qualified trade professionals working with hand-tool-appropriate fasteners. Inspect the wrench before use for cracks, chips, or worn ratchet action, and do not use a damaged tool. When working on energized or pressurized systems, follow applicable lockout\/tagout procedures before applying any fastener tool. Do not use extension bars or cheater pipes to increase leverage on a combination wrench, as this can overstress the tool and cause failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Offset Angle\u003c\/strong\u003e: 0 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\u003eHandle Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: Yes\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: Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: JSCR18T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542812950834,"sku":"JSCR18T","price":34.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3653a5d44ae0883192428c31d4192bea_b6b852ff-5b39-40ac-bf43-64c4df566db8.jpg?v=1785908140","url":"https:\/\/voomisupply.com\/products\/proto-jscr18t-9-16-inch-ratcheting-combination-wrench","provider":"Voomi Supply","version":"1.0","type":"link"}
