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
