Left-hand (LH) thread taps are among the hardest threading tools to source, and a key part of our specialist range. We supply left-hand hand taps, tap sets, pipe taps and dies in HSS uncoated, plus left-hand machine taps in HSS-E with uncoated, TiN and TiCN coatings, across Metric, Metric Fine, UNC, UNF, BSW, Whitworth Pipe (G) and NPT/NPTF standards. Because left-hand threads are far less commonly stocked than right-hand taps, most distributors cannot supply them off the shelf - our Dubai warehouse can, with fast dispatch across the UAE and GCC.

What Are Left-Hand Taps and Why Are They Hard to Source?

A left-hand tap cuts a left-hand (LH / reverse) thread that tightens counter-clockwise instead of clockwise. These threads are used wherever rotation or vibration would otherwise loosen a standard right-hand thread - for example on vehicle wheel studs, rotating and reciprocating shafts, lathe spindles, hydraulic and pneumatic fittings, packaging and textile machinery, and legacy or obsolete equipment. Because the vast majority of production threading is right-hand, left-hand taps, tap sets and left-hand machine taps are manufactured in far smaller quantities, which is why most general distributors cannot supply them off the shelf.

At DAH Marine we keep left-hand taps in Dubai stock and also source hard-to-find LH sizes on request. We supply left-hand hand taps and tap sets in Metric Coarse (M), Metric Fine (MF), UNC, UNF and BSW, left-hand pipe taps in Whitworth Pipe (G) and NPT/NPTF, and left-hand machine taps for CNC and manual production. Hand taps, tap sets, pipe taps and dies are supplied in HSS uncoated, while left-hand machine taps are available in HSS-E (cobalt) with uncoated, TiN (Titanium Nitride) and TiCN (Titanium Carbonitride) coatings - plus matching left-hand dies so you can repair or produce both the internal and external thread.

Left Hand Taps, Left-Hand Tap Sets & Machine Taps in Dubai, Abu Dhabi & the UAE

DAH Marine is a specialist source for left-hand taps, left-hand tap sets and left-hand machine taps in the UAE. Our Dubai warehouse carries LH hand taps and tap sets in Metric (M) and Metric Fine (MF), plus imperial UNC, UNF and BSW, and left-hand pipe taps in Whitworth Pipe (G) and NPT/NPTF. Whether you need a single left-hand tap for an emergency repair, a left-hand tap and die set for a workshop, or production left-hand machine taps for a CNC cell, we provide quotations, stock checks and fast dispatch across Dubai, Abu Dhabi, Sharjah and GCC export markets.

Left-hand threads are common in hydraulic and pneumatic systems, rotating and reciprocating machinery, vehicle wheel studs, packaging equipment, lathe spindles and legacy machines. Most suppliers do not stock them, which makes a reliable left-hand tap supplier in Dubai essential for maintenance and production teams. We supply left-hand hand taps and tap sets in HSS uncoated, left-hand machine taps in HSS-E with uncoated, TiN and TiCN coatings, plus matching left-hand dies, and can source non-standard and hard-to-find LH sizes on request.

How to identify a left-hand tap: left-hand taps are usually marked 'LH' on the shank and often have a groove machined into the shank face. If you hold a tap vertically and the threads slope down to the left, it is a left-hand tap. Send a clear photo of your sample and our team will confirm the thread size, pitch, standard and direction so you receive the exact left-hand tap you need.

Left-Hand Taps FAQ

What is a left-hand tap?
A left-hand tap cuts a left-hand (reverse / LH) thread that tightens counter-clockwise. It is used wherever rotation or vibration could otherwise loosen a right-hand thread, such as wheel studs, rotating shafts, hydraulic and pneumatic fittings, and reciprocating machinery.
Do you stock left-hand tap sets?
Yes. We keep left-hand hand tap sets in Dubai stock in metric (M, MF) and imperial (UNC, UNF, BSW, G, NPT) standards in HSS uncoated, plus left-hand machine taps in HSS-E with uncoated, TiN and TiCN coatings, and matching left-hand dies.
How do I identify a left-hand tap?
A left-hand tap is normally marked 'LH' on the shank and has a groove cut into the shank face. As a quick check, threads that slope down to the left when held vertically are left-hand threads. Send a photo of your sample and we will confirm the exact size and standard for you.
Where are left-hand taps used?
Left-hand threads are used on vehicle wheel studs (driver-side), rotating and reciprocating machinery, lathe spindles, packaging and textile equipment, hydraulic and pneumatic fittings, and any application where right-hand rotation could self-loosen a standard thread.
Can you supply left-hand taps as single sizes?
Yes. In addition to sets, we supply individual left-hand taps in the exact thread size, pitch and standard you need, including non-standard and hard-to-find LH sizes, with fast dispatch from Dubai across the UAE and GCC.
