It accepts taps ranging from 5\/16 inch to 3\/4 inch, covering a wide range of threading tasks encountered in mechanical, plumbing, and HVAC fabrication work. At 16 inches in overall length, the wrench provides the leverage needed for controlled torque application without over-driving threads. The non-ratcheting straight handle design gives the technician direct feel and precise control through each rotation. This tool is standard equipment for pipefitters, machinists, and maintenance technicians who cut threads on the bench or in the field.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 50422 is suited for use in residential and commercial trade environments where field threading or repair tapping is required. It handles pipe tap sizes from 1\/8 inch to 1\/2 inch, making it a practical tool for plumbing roughin, HVAC bracket fabrication, and general mechanical maintenance. The straight handle configuration works well in open bench settings where full rotation is accessible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTap capacity range of 5\/16 inch to 3\/4 inch for versatile threading applications\u003c\/li\u003e\n  \u003cli\u003ePipe tap range of 1\/8 inch to 1\/2 inch for plumbing and pipefitting tasks\u003c\/li\u003e\n  \u003cli\u003e16-inch overall length delivers extended leverage for controlled thread cutting\u003c\/li\u003e\n  \u003cli\u003eStraight handle style for direct torque feedback and full-rotation use\u003c\/li\u003e\n  \u003cli\u003eNon-ratcheting mechanism for precise, deliberate tap advancement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight-handle tap wrench compatible with standard straight-shank hand taps in the 5\/16 inch to 3\/4 inch range.

Secure the workpiece firmly before tapping to prevent movement and ensure thread alignment. Apply appropriate cutting fluid for the material being tapped to reduce friction and extend tap life. Do not force the tap — back off periodically to clear chips and prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Capacity\u003c\/strong\u003e: 5\/16 to 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Tap Range\u003c\/strong\u003e: 1\/8 to 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111720\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541457142066,"sku":"50422","price":287.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00b55e72c1cd9b609012b20660a495c4.jpg?v=1785876650","url":"https:\/\/voomisupply.com\/products\/starrett-50422-straight-handle-tap-wrench-5-16-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
