It features a 1\/2 inch square drive and fits an 18 mm hex fastener with a 25.4 mm socket size. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding. At 0.35 pounds, it is compact and easy to handle in tight service spaces. Licensed tradespeople and experienced technicians reaching recessed or angled fasteners in equipment panels, pipe assemblies, and electrical enclosures will find this socket useful for day-to-day service calls.\u003c\/p\u003e\n\u003cp\u003eThis socket suits residential and light commercial trade work where metric fasteners are common — including HVAC equipment cabinets, condenser units, pump housings, and panel enclosures. The universal extension design allows access to fasteners that are offset or difficult to reach with a standard socket. It is compatible with any 1\/2 inch drive ratchet, torque wrench, or breaker bar. Sold individually, it can be added to an existing socket set or carried as a dedicated replacement for a specific fastener encountered regularly on a service route.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 mm hex size for metric fastener applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch square drive fits standard ratchets, torque wrenches, and breaker bars\u003c\/li\u003e\n  \u003cli\u003e6-point design reduces fastener rounding under high torque\u003c\/li\u003e\n  \u003cli\u003eUniversal extension style for angled or offset fastener access\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.35 pounds for easy one-handed use\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit — no minimum bulk order required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any standard 1\/2 inch drive ratchet or torque wrench.

Always de-energize electrical equipment and isolate fluid systems before loosening or torquing fasteners in live service panels or pressurized assemblies. Inspect the socket for cracks or wear before each use and do not use it with impact drivers unless the socket is rated for impact use. Follow applicable codes and equipment manufacturer torque guidance when fastener preload is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Universal Extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch square drive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 25.4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111704\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: APEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KH-8-18M-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APEX","offers":[{"title":"Default Title","offer_id":51541967569202,"sku":"KH-8-18M-6","price":176.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d3760b761e8a7672c0e07b87cf1f6c7.jpg?v=1785888580","url":"https:\/\/voomisupply.com\/products\/apex-kh-8-18m-6-universal-extension-socket-18mm-1-2-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
