It accepts a 10 mm hex bit and measures 1-49\/64 inches in overall length, making it suitable for fastener access in confined spaces. This socket is intended for professional hand-tool applications across mechanical, HVAC, plumbing, and electrical service work where hex-drive fasteners are common. At 0.12 pounds, it is a lightweight single-piece tool built for repetitive fastener-driving tasks in both shop and field environments.\u003c\/p\u003e\n\u003cp\u003eThis hex bit socket fits standard 3\/8 inch drive tool setups and is appropriate for residential and commercial service work. It is well suited for technicians who routinely encounter 10 mm hex fasteners on equipment panels, motor mounts, access covers, and similar hardware. The 1-49\/64 inch overall length provides clearance in moderately confined installations without sacrificing drive engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch drive interface compatible with standard ratchets, extensions, and torque wrenches\u003c\/li\u003e\n  \u003cli\u003e10 mm hex bit size for precise engagement on metric hex fasteners\u003c\/li\u003e\n  \u003cli\u003e1-49\/64 inch overall length suits tight-clearance applications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.12 pounds for reduced hand fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece socket construction for consistent torque transfer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-fitment hex bit socket for use with any 3\/8 inch drive hand tool, including ratchets, breaker bars, and torque wrenches that accept square-drive accessories.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand tool technicians across mechanical and service trades. Confirm the drive square is fully seated before applying torque to avoid slippage or fastener damage. Inspect the hex bit socket for wear or rounding before use, particularly on high-torque applications. No power tools should be used with a hand-rated socket unless the socket is explicitly rated for impact use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Hex Bit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-49\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: J4990-10MST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540385759538,"sku":"J4990-10MST","price":24.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1811f4bdc083d03bc8386a091b31ab5f.jpg?v=1785853885","url":"https:\/\/voomisupply.com\/products\/proto-j4990-10mst-hand-hex-bit-socket-3-8-in-drive-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
