Robertson Screwa

[ian Simpson]

Our 1928 Tudor is Canadian built. Whomever restored it some years ago replaced many of the Robertson screws with US style slot head screws. Although the car is a long way from a show model, I would like to replace the most visible screws with Canadian style to avoid embarrassing comments from fellow club members.

Does anyone know of a source for a suitable set of Robertson screws?

My apologies if this duplicates previous posts.

Call Robertson, I called the HQ several years ago, they gave me the name and number of a gentleman in BC who does MAFCA seminars on Robertson screws. I have since lost his info, but he was very helpful, even asking if I could send hardware to him so Robertson could match them.

Also, Les Pearson in NZ does or did have hardware also.

Dixie Upholsteries in Kitchener, Ontario has Robertson Screw Kits set up for most Canadian Model A body styles. www.dixies.ca I have purchased some from them

There is also a Model A parts supplier in the US that also has Robertson Screw Kits for Canadian cars, but I can not recall the company name at this time

You may also contact George Moir in Stoney Creek, Alberta, to see what he may have. www.georgemoir.ca

One of the most distinctive features of the Canadian built
Model A Was the use of square socket drive screws instead
of standard slotted head machine and wood screws. These
fasteners were supplied by the P.L. Robertson Company
of Milton, Ontario for the Canadian Model A and were
frequently used in many places on Canadian bodies, but
not exclusively. Some body styles were shipped into
Canada for assembly and used both American and
Canadian made fasteners.

Actually this fellow worked for Robertson. I believe he did a seminar during a MAFCA National Convention in Vancouver, British Columbia about 2010. Maybe some one remembers.

Dixie Model A Parts in Kitchener has Robertson screw kits for sure. I bought a set from them for a Fordor. Wayne

Note: The Robertson screws were not a "square" drive, rather each socket and bit had a distinctive matched taper similar to a "morse taper" that allowed the screw to be held by the bit. A real neat innovative design.

Ian,
I bought a Canadian build 29 phaeton about 7 years ago. I was surprised that it had about half Robertson head fasteners and half slotted fasteners. I think some parts of the car were assembled in the US (slotted fasteners) and the remaining assembly was done in Canada. I am almost positive from the condition of the slotted fasteners, they had never been replaced. Just for your information.

If the square bits do not fit.

Where does one get a bit for these screws here in the "lower half" ?

Home Depot, Lowes, Amazon . . .

The Robertson drivers range in size #00, #0, #1, #2, #3 and #4.

When restoring my Canadian Roadster, the lower stanchions used #4 which is not commonly available, even in Canada. I had to order the #4 driver bit directly from Roberston, Inc in Milton, Ontario.

Interesting to note that if P. L. Robertson hadn't turned down Henry Ford for exclusive rights on these screws, US built Model A's would have them.

My 1930 Canadian Standard Phaeton also has a mismatch of Robertson and flat blade screws. The most interesting is that the Front door hinge screws are Robertson, the rear doors use Flat blade screws.

Some claim this body was made in Detroit, others say it was assembled in Canada, but that discussion I'll save for another thread.

Just quoting the restoration guidelines.
