Tolerance

The nominal diameter of sleeve is also the nominal diameter of the receiving bore. Tolerance on the receiving bore shall be H12. We recommended use of hydraulic pressure in assembling the Dowel in order to minimize damage to the receiving bore and the pin.

Material

Dowel Pins are manufactured out of Spring Steel 75 C 6 as per IS 2507 - 1975. hea-treated to 47 to 51 HRC. (Also see note)

Surface Finish

Generally all Dowels Pins are thermally blackened. We also provide Zinc and Phosphate surface protection.

Resilience and Recovery Test

Resilience and recovery shall be tested by driving the sleeve ten through a hole of nominal size, within the tolerance zone H6 in a hardened steel plate of St 60. The maximum reduction in the oversize of the diameter shall not exceed 50 percent of the oversize in delivery condition. For example, the outside diameter shall not be less than 20.25 mm on reduction from 20.5 mm for a spring dowel pin of 20mm nominal diameter.

Quality Assurance

All Dowel pins are thoroughly inspected for Dimensions like Outside Diameter, Inner Diameter, Length, Length, Thickness, Longitudinal gap, Chamfer Length and Hardness according to IS:5988, DIN 1481 or as per party's specification. Dowel are checked for resilience and recovery test in order to ensure better service life

Note

We manufacture Dowel Pins of Ø 18mm Nominal in En 45 grade. Also please note that the resilience and recovery Test is applicable to Dowell made of En 45 grade only.

Please see Table 1 and Table2 for Preferred Lengths and Tolerance of Length respectively. Any other length tolerance can be given as per party's specification. For further details contact Marketing Cel
