Bow roller anchor gate

[Mike Thompson]

I have a Bruce anchor which when not in use is held in the bow roller
by a steel shaft that goes though an eye on the anchor. This steel shaft passes though the two sides of the bronze bow roller fitting. To release the anchor
I rotate the shaft and pull it out of anchor. There is a pin that goes
though the shaft to prevent the shaft coming right out of the roller fitting.

Unfortunately this pin has disappeared. I never paid much attention to
it so I have no idea of what kind of pin it was.

Cna anyone help here?

Different part, same solution...call Spartan.

I have replaced that pin several times. I have no idea what it is called. I get it at the local hardware store. Obviously it is quite small. It is squeezed into the hole with pliers. The pin has no provision for a screwdriver. It is more like a nail with grooves that wind around the shaft that and are not screw threads. It is not pointy. This description and the shaft with its hole should get you the part at a decent hardware store. Cost about $.05. get several since they need to be installed while you dangle on the pointy end of your boat.

I believe roll pins are what you are talking about. See the following: http://www.engineersedge.com/roll_pin.htm

Leonard,
Thanks for your help but I went to two local hardware stores and they
didn't have or naything like it.

Ray,
Yes, maybe a roll pin might do the job, however I remember the old
pin had a shiney round head.

Tomorrow I'll phone Sparten.

roll pins (also called tension pins) are NOT the pin that fits this application. I will go to hardware store monday and get the name for you.

...a Ball-Lok Quick Release Pin?

Most any marine supply house will have them (West, Defender, Hamilton, etc)

I rotate the shaft and pull it out of anchor. There is a pin that goes

Sounds like the right place for a roll pin to me. Thats what I have on my CD. Sorry if I confused things.

went to hardware store.. they rearranged their offerings into new neat preprinted boxes... and i could no longer find those little buggers. a tiny screw of the same size will not likely work since the correct part is mallable and is squeezed not screwed into the tiny hole. but you might try it.

spartan marine does include this pin when you buy the whole
sliding shaft. see he 'missing pin" thread below.

a roll pin. See Ray's link for a picture. They don't have a "round shiney head", though.

My Honda 5 outboard has roll-pins in the mounting clamps, connecting the plastic handles to the clamping screws. Sounds like a good idea, but they tend to vibrate out despite squeezing themselves *very* tightly in the hole.

A small, s/s rivet would work if the hole in the lock pin is enlarged on the inside...not a pop rivet, the old-fashioned "bash with a hammer" type.

[Mike Thompson]

Thanks for all your suggestions.

Here is the answer. It is a Knurled Studded Drive Pin.
Spartan sent me three of these pins at no charge.
Three because it is very likely to loose one or two while trying to put
them in while hanging over the water.

They are about a quarter inch long and function a bit like a rivet.

I'm told to put a block of steel under the shaft to receive the pin
and then to hammer it in with a smart wack from a ball-peine
hammer.

Seems like some Loctite would be appropriate here. Can you squeeze the pim in with a pair of vise grips so you don't have to try to hammer in a difficult position?
