The wrench features a 12-point box end with a 15-degree offset head angle, allowing engagement in confined spaces where full rotation is not possible. The ratcheting mechanism eliminates the need to reposition the tool on each stroke, improving efficiency on repetitive fastener work. Constructed from steel with a corrosion-resistant chrome finish, it meets ASME standards. Overall length is 5 inches and the tool weighs approximately 0.09 pounds. It is tether capable, making it suitable for use at height or in environments where dropped-tool protocols are enforced.\u003c\/p\u003e\u003cp\u003eThe JSCV10F is suited for mechanical, electrical, plumbing, and HVAC service work where 5\/16-inch fasteners are common. The compact 5-inch overall length and flexible 15-degree offset head make it practical for equipment panels, junction boxes, and tight equipment compartments. Tether-capable construction supports compliance with dropped-object prevention programs on commercial job sites, elevated work platforms, and industrial facilities. It is appropriate for both residential service calls and commercial maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-point ratcheting box end for efficient operation in limited-swing situations\u003c\/li\u003e\n\u003cli\u003e15-degree offset head angle improves access in confined spaces\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant chrome finish on steel construction\u003c\/li\u003e\n\u003cli\u003eTether capable for dropped-object prevention compliance\u003c\/li\u003e\n\u003cli\u003eMeets ASME standards for combination wrenches\u003c\/li\u003e\n\u003cli\u003eCompact 5-inch overall length for tight-clearance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/16-inch combination wrench suitable for use with 5\/16-inch hex fasteners across residential and commercial mechanical, HVAC, plumbing, and electrical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is a hand tool used by HVAC technicians, electricians, plumbers, and general mechanical trades. Always de-energize electrical equipment and shut off fluid or gas supplies before working on fasteners in live systems. When used at height or in environments with dropped-tool policies, attach an appropriate tether lanyard to the tether point before use. Inspect the ratcheting mechanism for smooth operation before each use and do not apply extension bars or pipe to the handle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Offset 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\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\u003eTether Capable\u003c\/strong\u003e: Yes\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\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.5 inches L x 1.8 inches W x 1.02 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: JSCV10F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541070545202,"sku":"JSCV10F","price":43.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ee7eaa78cc57c3f9ec0f8254c2837ef.jpg?v=1785868104","url":"https:\/\/voomisupply.com\/products\/proto-jscv10f-5-16-inch-ratcheting-combination-wrench","provider":"Voomi Supply","version":"1.0","type":"link"}
