It features a 15-degree offset box end that improves knuckle clearance in tight spaces, paired with an open end on the opposite side for fast fastener engagement. The wrench is machined from steel with a corrosion-resistant finish and meets ASME B107.100-2010 standards. At 3.75 inches overall length and 0.08 pounds, it is compact and light enough for belt pouches or tool rolls. The tether-capable design supports use in elevated or overhead work environments where dropped tools are a safety hazard.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for residential and commercial service work across HVAC, plumbing, electrical, and general mechanical trades. Its compact overall length makes it practical for working around equipment panels, pipe fittings, and electrical enclosures where standard-length wrenches cannot reach. The 12-point box end engages fasteners at multiple angles, reducing the need to reposition the wrench in restricted clearances. Tether-capable construction makes it appropriate for elevated work platforms and service on rooftop units or overhead installations where tool retention is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch head size fits standard fractional fasteners common in HVAC, plumbing, and mechanical applications\u003c\/li\u003e\n\u003cli\u003e15-degree offset box end improves knuckle clearance in tight or restricted spaces\u003c\/li\u003e\n\u003cli\u003e12-point box end allows engagement at multiple fastener positions with minimal swing arc\u003c\/li\u003e\n\u003cli\u003eTether-capable design supports use in elevated or overhead service environments\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant steel construction for durability in field conditions\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.100-2010 standards for combination wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard fractional combination wrench for use with 3\/8-inch fasteners in HVAC, plumbing, electrical, and general mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is a hand tool suitable for use by any licensed trade professional. Always ensure the wrench is fully seated on the fastener before applying torque to prevent rounding. When working at height or on elevated equipment, attach a tether to the integrated tether point per applicable fall-protection and dropped-object prevention guidelines. Inspect the wrench before each use and remove from service if cracking, deformation, or significant corrosion is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 3\/8 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\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 inches L x 1 inch W x 0.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.100-2010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: J1212ESB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540548911410,"sku":"J1212ESB","price":25.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c65fc744b1070c990c9dffd9b896f4f1.jpg?v=1785858198","url":"https:\/\/voomisupply.com\/products\/proto-j1212esb-combination-wrench-3-8-inch-12-point","provider":"Voomi Supply","version":"1.0","type":"link"}
