NOTES:

1. Dimensions are in inches.

2. Millimeters are given for general information only.

3. Angular orientation of this terminal is undefined. Square or radius on end of terminals is optional.

4. Diameter variations within these limits are permitted.

5. The ANSI thread reference is 0.190-32 UNF-2A.

6. Max pitch diameter of plated threads shall be basic pitch diameter 0.169 inch (4.29 mm) reference FED-STD-

H28 (Screw Thread Standards for Federal Services.)

7. Units must not be damaged by torque of 15 inch-pounds applied to 0.190-32 UNF-2B nut assembled on

thread.

8. Complete threads to extend to within 0.078 inch (1.98 mm) of the seating plane.

9. Terminal-end shape is unrestricted.

10. Reversed (anode to stud) units shall be marked with an "R" following the last digit in the type number.

11. Forward polarity (cathode to stud) marking is shown.
