Manufactured from malleable iron meeting ASTM A-197 chemical and physical property standards, it carries a galvanized finish per ASTM A-153 for corrosion resistance in wet or outdoor environments. Threads conform to ANSI B-2.1 pipe thread standards, and dimensions meet ANSI B-16.3. Sold individually, this lock nut is a standard item for plumbers and pipefitters working on threaded iron pipe assemblies in commercial and residential applications.\u003c\/p\u003e\n\u003cp\u003eThis lock nut is suited for use in water supply, gas distribution, and general-purpose threaded pipe installations where a secure mechanical connection is required. It is commonly installed at unions, fittings, and pipe terminations where vibration or backpressure could loosen standard connections. The galvanized coating makes it appropriate for damp or corrosive service environments. Licensed plumbers and pipefitters install this fitting on Schedule 40 and standard-weight threaded black or galvanized iron pipe systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction per ASTM A-197 for strength and machinability\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish per ASTM A-153 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eThreads conform to ANSI B-2.1 pipe thread standard\u003c\/li\u003e\n  \u003cli\u003eDimensions meet ANSI B-16.3 and Fed.
