It features a 12-point ratcheting box end with a reversing mechanism and a 15-degree offset head angle, allowing faster fastener cycling without repositioning the wrench. The open end is fixed at a 15-degree angle as well. Constructed from steel with a chrome finish, the JSCV10S measures 3.5 inches in overall length and is rated to ASME standards. It is also tether-capable, supporting dropped-object prevention programs on job sites where tool-tethering is required.\u003c\/p\u003e\n\u003cp\u003eThis wrench is suited for use in mechanical, plumbing, HVAC, and electrical applications where 5\/16-inch fasteners are common. Its compact 3.5-inch length and offset head design make it practical for confined-space work on equipment panels, junction boxes, pipe fittings, and mechanical assemblies. The ratcheting and reversing box end reduces hand movement during repetitive fastening tasks, which is especially useful in production environments or service calls requiring high fastener counts. Tether-capable construction makes it appropriate for elevated work and safety-sensitive sites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-point ratcheting box end with reversing mechanism for efficient fastening and removal\u003c\/li\u003e\n  \u003cli\u003e15-degree head offset angle on both ends for clearance in confined areas\u003c\/li\u003e\n  \u003cli\u003eTether-capable design supports dropped-object prevention programs\u003c\/li\u003e\n  \u003cli\u003eChrome finish over steel construction provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME standards for hand tool performance and dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eCompact 3.5-inch overall length suited for tight-access applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-inch fasteners in standard SAE applications across HVAC, plumbing, electrical, and general mechanical service work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is intended for use by qualified tradespeople familiar with hand tool safety practices. Before servicing any equipment, de-energize electrical systems per NFPA 70E lockout\/tagout procedures and shut off fluid or gas supply as required by applicable codes. Inspect the wrench for cracks or damage before each use and do not use it as a striking tool or extend it with a cheater bar. When using in tethered applications, attach an approved lanyard to the tether point before working at elevation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 5\/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\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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1\/4 inches\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: Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReversing\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.1 inches L x 1.77 inches W x 0.98 inches H\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: JSCV10S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542932029746,"sku":"JSCV10S","price":30.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f75544f942d102ab2edcd006d48face.jpg?v=1785911406","url":"https:\/\/voomisupply.com\/products\/proto-jscv10s-combination-wrench-5-16-inch-ratcheting","provider":"Voomi Supply","version":"1.0","type":"link"}
