SS Hex Weld Nuts DIN 929 
A weld nut is a special type of nut specifically designed to be welded to another object. There are various types for different applications.
These nuts are very similar to standard hex nuts, but have a locating boss and welding projections. The bosses also keep weld spatter out of the threads.
Hex weld nuts are a six-sided, internally threaded fastener with three triangular weldable projections on the top surface of every other corner of the fastener. The threaded hoe runs through the centre and has a pilot for the entire circumference of the opening which extends above the top surface of the nut and the above projections. The remainder of the top surface of the nut is flat.
We have a ready range of Hex Weld Nuts.
- Size Range: M4 to M12
Materials – Carbon Steel; Stainless Steel AISI-304/ AISI-316 - Datasheet
SS Hex Left Hand Nuts DIN 934
Left Handed Hex nuts are a general purpose nut, six sided, with internal screw threads. They look like regular nuts but are threaded opposite of standard nuts (right-hand), they have left hand thread. Hence, they turn counter-clockwise to install and tighten. Also known as “LH” (for left-hand), these nuts are used with left hand threaded bolts, screws, studs and threaded rod. These nuts are not compatible with right handed bolts.
SS Hex Long Nuts DIN 6334
A long nut used to connect pieces of threaded rod or other male threaded fasteners. is widely used for high-end industrial purpose and automobile industry. It can be manufactured using nickel alloy, stainless steel, steel alloy and duplex steel. It is partially threaded and offers tear and wear resistance, cost effectiveness and long functional life.
