It accepts a 3\/8 inch square drive and drives a 5\/16 inch hex fastener. Overall length is 1-13\/16 inches with a 3\/4 inch bit length, making it a compact tool suited for tight-clearance work. Licensed mechanics, HVAC technicians, plumbers, and electricians use this type of socket when precise hand torque is needed on hex-head fasteners, set screws, and similar hardware. The short profile reduces interference in confined installations.\u003c\/p\u003e\n\u003cp\u003eThis hex bit socket fits standard 3\/8 inch drive hand ratchets, T-handles, and breaker bars. It is appropriate for residential and light commercial service work where hex fasteners appear on equipment panels, valve packing glands, fan assemblies, and electrical enclosures. The 5\/16 inch hex size is common across a wide range of HVAC, plumbing, and electrical hardware encountered in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch square drive for compatibility with standard hand ratchets and drive tools\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex bit size for direct fastener engagement without an adapter\u003c\/li\u003e\n  \u003cli\u003eCompact 1-13\/16 inch overall length suited for restricted-access fastener locations\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch bit length provides adequate engagement depth on typical hex fasteners\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 for use with standard 3\/8 inch drive hand tools including ratchets, T-handles, and extension bars.

Verify the hex bit is fully seated in the fastener recess before applying torque to avoid rounding the fastener head. When working near energized electrical components, de-energize and lock out equipment per applicable NFPA 70E procedures before using any hand tool in the work area.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 5\/16 inch (7.9375 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Length\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Hex Bit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: J49905\/16ST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51538390581554,"sku":"J49905\/16ST","price":23.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fbee95038cfac3f01f0bd6c18f2bc4a.jpg?v=1785824225","url":"https:\/\/voomisupply.com\/products\/proto-j49905-16st-hand-hex-bit-socket-3-8-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
