Brass Nuts
Bharti Enterprise manufactures high-performance brass nuts engineered for precision, strength and vibration resistance. Machined from IS 319 (Type 1), BS 249 and CZ121 brass grades, they combine accurate six-sided geometry with clean threading for tight, reliable locking.

Engineered, not just supplied.
The range covers hex, slotted round, union, check, dome, eye, square and grooved lock nuts — plus nickel-plated locking variants — in sizes from M2 to M30 and threads from ISO Metric to UNC/UNF, BSW and BSP. Special nuts are also produced in copper, aluminium and steel where different mechanical or thermal properties are required.

Brass Nuts — answered.
The questions engineers and buyers ask us most. Something missing? Ask us directly — a specification answer costs nothing.
01What are brass hex nuts used for in electrical and mechanical assemblies?
Brass hex nuts are used in electrical switchboards, panel assemblies, plumbing fittings and machine components. Their conductivity, corrosion resistance and non-magnetic behaviour make them the reliable choice for electrical and electronic fastening.
02How are brass lock nuts different from standard hex nuts?
Brass lock nuts add internal thread-locking features or grooves that prevent loosening under vibration or thermal cycling. They are specified for transformers, motors and automotive systems where the joint must stay tight.
03Are Bharti Enterprise brass nuts compliant with international thread standards?
Yes. Nuts are manufactured in ISO Metric (DIN), UNC, UNF, BSW, BA and custom thread standards, precision-machined and inspected to ISO 965 tolerance classes for dimensional accuracy.
04What are brass dome nuts used for?
Brass dome nuts (acorn nuts) close off and protect exposed threads. They are common in electrical terminals, plumbing assemblies, battery packs and visible hardware where safety and finish both matter.
05Do you offer nickel or chrome-plated brass nuts?
Yes — nickel, chrome and silver plating are available for extra corrosion protection, conductivity and appearance. All plating is RoHS and REACH compliant, suitable for marine, telecom and premium hardware.
06What thread sizes can Bharti Enterprise produce in brass nuts?
From M2 to M30 in Metric and #4-40 to 1 inch in UNC/UNF, plus custom sizes, pitches and multi-start threads to tight tolerances — manufactured in Jamnagar, India and exported worldwide.
07What is the difference between brass union nuts and check nuts?
Union nuts join two mating parts with sealing in pipe and tube fittings. Check nuts are thinner locking nuts that secure fittings against loosening — typically in vibration-prone hydraulic or pneumatic assemblies.
