What is the difference with H for taps?
The difference in size from one H limit to the next is 0.0005″ increments for taps through 1″ diameter. Sizes over 1″ diameter are separated by . 001″ diameter increments. If the threads in the part are too loose, smaller numbers such as H1 or H2 are used.
What does H3 thread limit mean?
H3 = Basic Plus 0.0010″ to Plus 0.0015″
What does the H stand for on taps?
H means (high) above basic pitch diameter and L (low) below basic pitch diameter. Tap limits have been established to provide a choice in the selection of the tap size best suited to produce the class of thread desired.
What is 6H in tapping?
The metric thread 8mm of ISO standard is referred to as m8 and the tolerance of threaded hole is referred to as 6H.
What is a 6g thread tolerance?
Grade 6 is used for a medium tolerance quality and a normal length of thread engagement. Grades lower than 6 are intended for fine tolerance quality and/or short lengths of thread engagement. Grades higher than 6 are intended for coarse tolerance quality and/or long lengths of thread engagement.
What does 6H thread mean?
For example: M12 x 1 – 6H/5g6g indicates a tolerance class of 6H for the nut (female) thread and a 5g tolerance class for the pitch diameter with a 6g tolerance class for the major diameter. Grade 6 is used for a medium tolerance quality and a normal length of thread engagement.
What kind of tyres does a trek domane have?
In its most recent update, the Domane took notes from the Madone with an aero fork profile, whilst becoming more versatile thanks to clearance for 38mm tyres (without mudguards, 35mm with). It also gained a downtube compartment for stashing tools (or snacks!).
What kind of fit does a Trek bike have?

What does optimum compaction mean on a Trek bike?
Optimum Compaction refers to the way sheets of carbon are layered into the mould, and optimised via heat and pressure – in Trek’s opinion the two treatments are administered to the perfect ratio. Low Void refers to the minimisation of space between the layers of carbon, which might otherwise reduce strength and durability.
What’s the difference between a trek SL and SLR?
The weight difference is largely achieved by the use of700 Series OCLV carbon on the SLR, as opposed to 500 series on the SL. The aluminium model has seen some major work and the result earned it a place in the Editor’s Choice 2019 awards.
