CMA rules state that the maximum head height can be no more that 1/4 inch. Do the MF44 heads comply?

CMRC rule say 7.25mm head, and we are at the maximum height.

Do you know if the CMA say anything about a maximum height from the tire?

Because our washer is smaller than any other screw when the screw is install on the tire, the height of the screw from the rubber is the same height or lower.

Do you know if they talk about only the head ?? about the washer or total head height.??

We can make a screw that can meet any rules.

If you can send me a PDF of the CMA rules book, I would really appreciate.

Regards

I'll post a copy of the rules. I believe the 1/4 inch is from the rubber to the top of the head, including the washer portion.

When you get a chance please post a photo or two of you and those fast easterners racing. I know I have seen some shots of you in Canadian MX magazines and you guys put on a great show over there.

Here are the rules, this is from my '05 CMA Rule Book. I don't think there has been any changes regarding screws.

(f)(i)
The height of the stud head and any incorporated washer must not exceed 1/4".

(ii)
The "Production" stud must be flat (or almost so) across its total width, with the exception of the production lip. The maximum depth of the lip from the flat head surface shall be 35 thousands of an inch. Minimum width of head 3/16" maximum width of head 5/16".

(iii)
Production slotting or cutting which was originally intended to provide a method of inserting the screw (such as a screw driver slot or a Phillips driver depression) is permitted. Multi insertion slots are not permitted, nor is cross cutting allowed.

(iv)
However, cone shaped , claw shaped, hollowed, or special shaped or sharpened heads (except noted as below) will not be allowed regardless of the quantities these may be "produced" in.
Studs which comply with all of the shape and design factors shown in this rule book may be modified to the extent that filing (not grinding) across the flat surface of the head ( including the production lip) will be permitted. The filing must be done on a plane parallel to the standard stud head contour, ie. at a 90 degree angle to the vertical line of th threaded portion of the stud.

(v)
Production studs may not have a washer or other device added under the head on the outside of the tire, regardless of the fact they could still meet the 1/4" height measurment.

(vi)
The Referee shall have the authority to decide what constitutes a "legal stud" under this rule. His decision is subject to appeal to the Region Competition Committe after the race meet where the stud is found to be illegal.

(vii)
On oval tracks front tires may not be studded on the right outside third, (does not apply to ATVs).

Tks for the info.

We are over 1/4" (=0.250") height, CMRC permit 7.25mm (=0.297")

Thats mean that Holliday do not meet the CMA rules, the height is over 1/4" !!

Merry Christmas and happy new year

You are correct about Holliday screws, yet most guys run them or Kold Kutters. I have asked our club if the M44 screw can be used, hopefully they will make a decision quickly.

And Merry Christmas to you as well. (I'll be soaking up some sun in Mexico Dec. 23 - 31)
