Hi. Have a guy asking for an Ultimatum Deadline action, and I don't have the 3lug bolt head dimensions.
If someone has one, can they please provide some measurements for me ? Metric or MAGA units are fine.
Dimension C is bolt body diameter, not bolt head diameter.
Thank you in advance for anyone who can help.
