1. Where specifying nominal size as a basic diameter, zeros preceding decimal and in the fourth decimal place shall be omitted.

*Non-preferred sizes, not recommended for use in new designs.

2.3.4 Effective Length. The effective length, L, (that portion of the pin length bound by the length of point on one end and the radius of crown on the other) on short dowel pins shall not be less than 75 percent of the overall length of the pin. For the pin lengths affected, it may be necessary to deviate from the specified dimensions by reducing the crown radius and height, or increasing the point angle, or both.

2.3.5 Straightness. Machine dowel pins shall be straight over the effective length within an accumulative total of 0.0005 in. per inch of length for nominal lengths up to and including 4 in., and within 0.002 in. total for all nominal lengths over 4 in.

Stanlok Straight Pins | ROLL PINS

Roll pins are manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are generated against the hole wall holding the roll pin securely in place. Standard roll pins are manufactured to ASME B18.8.2. Standard finishes for high carbon steel roll pins are either light oil or zinc. Roll pins are used for thousands of demanding industrial applications.

1. Where specifying nominal size in decimals, zeros preceding the decimal shall be omitted.

2. Maximum diameter shall be checked by GO ring gage. A1+A2+A3

3. Minimum diameter shall be average of three diameters measured at points illustrated. A min = 3

4. Sizes 5/8 in. (0.625) and larger are produced from AISI 6150H alloy steel, not AISI 1070-1095 carbon steel.

5. For additional requirements, please call Sales at Stanlok.
