SELF TAPPING SCREWS

To ensure self tapping screws can be easily identified, they are stored in a numerical sequence. The clear advantage of this system is that alternatives can quickly be found if say a slightly longer screw is needed. Always ensure the correct style and length of screws are used for a particular job.

Original Triumph part numbers are invariably superseded to part numbers in this sequence.

All self tapping screws are numbered as follows:

Prefix = SS

1^st Number: - 1 = English 2 = Metric

2^nd/3^rd Numbers: - Gauge Number or diameter in mm

4^th/5^thNumbers: - Length in 1/8^th of an inch or mm from under the head to the end, except countersunk screws where the depth of the countersink is included

6^thNumber: - Head type

1 = pan slot

2 = pan pozi

3 = cks slot

4 = cks pozi

5 = raised cks slot

6 = raised cks pozi

7 = flanged pozi

7^th Number : - Finish plus variations

1 = BZP

2 = chrome

3 = black

4 = BZP spire screw (no point)

9 = none standard variations
