Constructed from steel with a polished finish, this wrench delivers reliable grip on hex fasteners in confined spaces where an open-end wrench cannot seat properly. The 12-point design allows more engagement positions per revolution, reducing the arc needed to reposition the wrench. At 6.59 inches in length and 0.131 pounds, it is compact enough for tight quarters while providing sufficient leverage for standard fastener torque. Mechanics, pipefitters, HVAC technicians, and electricians reach for this tool when working on equipment panels, valve assemblies, and terminal hardware requiring fractional inch fastener sizes.\u003c\/p\u003e\n\u003cp\u003eThis wrench is suited for light mechanical and service work across residential and commercial applications. Common use cases include tightening or loosening small fasteners on HVAC equipment covers, electrical panel hardware, plumbing fixture connections, and instrumentation assemblies. The 1\/4 inch and 5\/16 inch ends cover two of the most common small fractional fastener sizes found on trade equipment. The polished steel finish resists surface corrosion under normal service conditions and allows for easy cleaning after use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides 1\/4 inch and 5\/16 inch box openings in a single tool\u003c\/li\u003e\n  \u003cli\u003e12-point box ends allow fastener engagement every 30 degrees for use in restricted swing areas\u003c\/li\u003e\n  \u003cli\u003eSteel construction with polished finish for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eNon-ratcheting design eliminates internal mechanism failure points\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.10 standards for hand tools\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4 inch and 5\/16 inch hex fasteners in fractional inch sizes.

Always ensure the wrench is fully seated on the fastener before applying torque to avoid rounding the fastener head. Inspect the tool for cracks or deformation before each use and do not use it as a striking tool or apply additional leverage extensions beyond the handle. Store in a dry location to preserve the finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Box End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/4 x 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\u003eEnd Configuration\u003c\/strong\u003e: Double End\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: Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.41 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.131 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: J8179-T500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51538308628786,"sku":"J8179-T500","price":58.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b52ea59944013ba1f824058cfc19dca.jpg?v=1785822583","url":"https:\/\/voomisupply.com\/products\/proto-j8179-t500-box-end-wrench-1-4-x-5-16-in-12-point","provider":"Voomi Supply","version":"1.0","type":"link"}
