These are planer blade/knife height adjustment screws that engage with the slots in the blade/knife.

One is particularly shabby and has been bodged as I assume the original went AWOL, this is how the machine came. There isn't really enough metal left to cut the slot deeper with grinding disc.

What are they named? I can't seem to find any? It's BSF thread and a solid piece.

I can't fabricate with BSF threaded bar and braze on a washer as I don't have the tools

Anyone have any ideas?

What size thread is it? It looks to be 7/32" by scaling it off the rule. Does the thread need to go right up to the underside of the shoulder?

I’d suggest anyone 10% competent with a metal lathe can make you some more pretty easily, probably not expensive if you find a little place

Hi Brian,

It’s 1/4” BSF - I’ve put a tap through the hole and it’s matches thread pattern.

No the thread doesn’t need to go all the way up to the shoulder.

Ahh I thought you were volunteering there Aiden! 😉

it’s hard to find places like that where I’m not going to be charged silly money for such a small part..
 
You can be sure to get them on ebay.
look for slotted (or slot head) machine screws in 1/4" bsf
 
Hi sunnybob,

I can’t be sure to find one on eBay. Ive had a very thorough look for some days but I’m not sure what this type of screw is called hence the title name of my initial post.

It’s like a cheese head Machine screw with an extra wide shoulder below the head for fitting into the planer blade/knife slot.

If you can find me one on eBay, I’ll eat my hat 😉

Might be best to go along personally i have always found that way you get to talk to someone that knows what he's talking about.
 
Hi Gremmy,
between me and my mate Bill we could make them for you. Send me a PM and we'll see what we can arrange
