Built from alloy steel with a black oxide finish, this socket fits a 3\/8 inch drive ratchet or breaker bar and turns 9\/16 inch fasteners. The 12-point configuration allows engagement at 30-degree increments, giving technicians more ratchet swing in tight spaces. Overall length is 1-1\/8 inches. The black oxide coating provides corrosion resistance under typical shop and field conditions. This socket meets ASME B107.1 standards and carries a limited lifetime warranty.\u003c\/p\u003e\u003cp\u003eThe J5218B is suited for residential and commercial maintenance tasks, automotive service, HVAC equipment assembly, electrical panel work, and general mechanical repair. Its compact 1-1\/8 inch overall length makes it practical in confined fastener locations where longer sockets would not clear surrounding components. Licensed technicians and experienced tradespeople working with 3\/8 inch drive tool sets will find this socket a standard-duty replacement or addition to an existing socket set.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/16 inch socket size for common SAE fastener applications\u003c\/li\u003e\n\u003cli\u003e12-point design engages at 30-degree increments for tighter working clearances\u003c\/li\u003e\n\u003cli\u003e3\/8 inch drive compatible with standard ratchets, extensions, and breaker bars\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME B107.1 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for corrosion resistance in shop and field environments\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty coverage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style hand socket for use with 3\/8 inch drive ratchets, extensions, and torque wrenches across general mechanical and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should follow standard hand-tool safety practices. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Do not use hand sockets with impact drivers or impact wrenches unless the socket is rated for impact use. This socket is not tether capable and should be secured appropriately when working at elevation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\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: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Not Tether Capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited Lifetime\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: J5218B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544580358450,"sku":"J5218B","price":15.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de63bc301e611fdc10d38b5e1ae73a77.jpg?v=1785930591","url":"https:\/\/voomisupply.com\/products\/proto-j5218b-9-16-inch-12-point-3-8-drive-hand-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
