It accepts a 20 mm fastener and features a 12-point opening, giving technicians more engagement positions in tight quarters. Constructed from polished steel and manufactured to ASME B107.21 standards, this socket is suited for general mechanical work across automotive, industrial, and maintenance trades. It measures 1-25\/32 inches in overall length and weighs 0.25 pounds. The polished finish reduces corrosion buildup and makes it easier to spot in a toolbox or on a workbench.\u003c\/p\u003e\n\u003cp\u003eThis socket is a practical choice for mechanics, millwrights, and maintenance technicians working with metric fasteners in the 20 mm range. Standard-length sockets like this one handle the majority of accessible fastener locations on engines, machinery frames, suspension components, and structural assemblies. The 3\/8-inch drive size keeps the tool compact while still delivering adequate torque for most mid-range fastener applications. It is sold individually and is not tether capable, making it appropriate for standard shop and field use where tethered tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 mm socket size for metric fastener applications\u003c\/li\u003e\n  \u003cli\u003e12-point design provides more indexing positions in restricted access areas\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch drive compatible with standard ratchets, extensions, and breaker bars\u003c\/li\u003e\n  \u003cli\u003ePolished steel construction meets ASME B107.21 standards\u003c\/li\u003e\n  \u003cli\u003eStandard length at 1-25\/32 inches overall for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eBacked by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or addition for 3\/8-inch drive socket sets requiring a 20 mm 12-point metric hand socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove fasteners using a 3\/8-inch drive ratchet, breaker bar, or torque wrench.
