Expansion bolts, pipe branch / crane / bracket or equipment fixed on the wall, floor, column used in a special thread connector. Carbon steel bolt level is divided into 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,12.9 more than 10 grades.
The figures before and after the decimal point indicate the nominal tensile strength and yield ratio of the bolt material, respectively. For example, a grade 8.8 bolt indicates that the tensile strength of the material reaches 800 MPa and the yield ratio is 0.8, ie, the yield strength reaches 800 × 0.8 = 640 MPa.
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.
