L-type hex keys are a standard hand tool for trade professionals who need to drive socket head cap screws, set screws, and similar fasteners encountered during HVAC equipment assembly, plumbing fixture installation, and electrical panel work. The L-shape design provides two usable ends: the short arm for torque and the long arm for reach and speed. These keys are a utility item kept on service vans and in tool kits across multiple trades.\u003c\/p\u003e\u003cp\u003eThe HK-3mm is suited for general trade service work where a 3 mm hex drive is required. The bag-of-25 format makes this a practical choice for shop stocking, fleet van replenishment, or job-site kitting where individual keys are prone to loss. Both HVAC technicians and plumbers regularly encounter 3 mm fasteners on equipment panels, valve packing nuts, and component mounting hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eL-type profile provides both torque leverage on the short arm and extended reach on the long arm\u003c\/li\u003e\n\u003cli\u003e3 mm hex drive size covers common fasteners found on HVAC, plumbing, and electrical equipment\u003c\/li\u003e\n\u003cli\u003eSold in a 25-count bag for efficient stocking and van inventory management\u003c\/li\u003e\n\u003cli\u003eCompact individual weight supports lightweight tool kit organization\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3 mm socket head cap screws and set screws across residential and light commercial trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHex keys are a hand tool requiring no power source or code-specific installation procedure. Select the correct 3 mm key before applying torque to avoid rounding fastener sockets. Do not use extension bars or pipes to increase leverage on L-type hex keys, as this can damage the fastener or the key. Replace any key that shows visible wear or deformation at the tip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: L-Type Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Bag\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HK-3mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51346748473650,"sku":"HK-3mm","price":19.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310543325.jpg?v=1782089169","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-hk-3mm-l-type-hex-key-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
