Trapezoidal thread, Acme thread and nuts available from T.E.A. Transmissions

T.E.A. Transmissions announces the availability of trapezoidal threads in
C15 carbon steel, including both right and left forms in various lengths up to
3000mm with longer lengths supplied on request.

T.E.A. Transmissions also offers stainless steel trapezoidal thread AISI
304/ 1.4301 and marine grade trapezoidal thread in stainless steel AISI
316/ 1.4401-4 on request. The company offers these products in standard sizes sourced
from their precision manufacturer overseas while non-standard sizes, and
left hand thread in various sizes, can also be supplied based on
requirement.

Nuts are available in steel, stainless steel, plastic and bronze
materials, in plain round, round with flange and mounting holes, hexagonal and
square options.

Being the imperial size alternative, Acme thread is sourced readily on
request. Buyers can provide product specification detail for quotation
including the outside diameter, threads per inch, length, quantity, and
material type together with nut specifications.

Trapezoidal threads feature a common screw thread profile offering high
strength with ease of machining and assembly. Typically these threads are found
where large load or accuracy is required as in vices where the thread is used
to supply compressional holding force or the lead screw of a lathe where the
thread is used to convert rotational motion into linear motion.

Similar to the Acme series, the trapezoidal thread and nuts are power
transmission screw threads made to metric dimensions and standards instead of
inch. The flank angle is a key difference between Acme and trapezoidal threads with
Acme threads having flank angles of 29¡ while trapezoidal threads feature 30¡
angles. All trapezoidal threads have lead angles of 5¡ or less making them self
locking, which prevents the screw from back-driving under most conditions,
eliminating the need for brakes or other holding devices.

The standard range of threads available from T.E.A.
Transmissions is cold formed using a unique, highly accurate thread rolling
process, which guarantees a smooth, high quality thread. The range of
applications for the trapezoidal thread spindles is expanded as it is possible
to choose from threads produced from steel or stainless steel, and nuts
produced from bronze, steel or stainless steel. Steel nuts are not intended for
motor driven motion screws, while bronze nuts provide superior service at
higher working loads.
