Expansion Bolt Specifications Indicate:
Bolt Size M14 indicates a metric thread of 14mm thread. M stands
for "metric, metric" thread. The complete thread mark is made up
of: Thread Feature Code + Size Code + Tolerance Band Code + and
Other Information + Standard Code(Such as: on the domestic screws
plus GB code)
1, the thread characteristics of the code letter "M"
2, size code
Single-thread size code for the "nominal diameter × torque." Coarse thread can be omitted marked with its screw moment. Multi-thread size code for the "nominal diameter × Ph lead
P-torque."
3, the tolerance zone code by the number of letters (the upper
thread of the female thread, the lower case of the male thread),
such as 7H, 6g, etc., should be particularly pointed out that 7H,
6g and so on behalf of thread tolerances, and H7, g6 represent
cylinder tolerance Code
4, the provisions of the screw length of the short (with S), in
(with N), long (L) three. Under normal circumstances, do not mark the screw thread length,
the thread tolerance band to determine the length of the medium
length (N). If necessary, add a spin length code S or L, eg "M20-5g6g-L". Special needs, you can indicate the value of the spin-on length,
such as "M20-5g6g-30".
5, left-hand thread should be marked with "LH" after the length of
the screw. Sewing length code and spin code with "-" separated, right-hand
thread omitted Note.
6, mark example:
M 16-5g6g said ordinary coarse thread, the nominal diameter of 16,
right-hand, thread tolerance with a diameter of 5g, diameter 6g,
screw length according to the medium length to consider.
M16 × 1 LH-6G said fine teeth ordinary thread, nominal diameter 16,
pitch 1, left-hand, thread tolerance band diameter, diameter are
6G, screw length according to medium length consideration.
