Finishing mucking with front seats again, cannot for the life of me find the screws (two with chrome heads?) which secure the seat rear chrome handles (as in picture) a single screw for each. Can anyone tell me the size, head type, thread and length I should be looking for? I have a million screws and cannot see the trees for the forest. broke phone camera so image is blah.

 

yeahh I know what you mean with those screws, fortunately I have the originals and they are not phillips.

but I can't tell what size or thread they are. .

 

are they long or short screws? i swear i remember what they look like but the more i look the less confident I am that I do.

 

i would say medium, not long not short.
they have to cross the recliner handle to reach the hole but just about 1/4" to 3/8" over into the hole..

 

Aden, How did you BREAK a Phone Camera?!
I have gone through Several phones which died for numerous and varied reasons, but the Cameras of all of them are still operative.
Curious minds ask hard questions............

screw in my seat recliner handle measures 5/8" long. It is a basic screw, nothing special. you should find two of the right thread.
I took a picture of it but I cannot start my laptop, and this forum does not let me insert pictures from my phone, been dealing with that issue and I don't kbow what has happened.
I could only insert pictures through my laptop and it looks like the power supply is dead.

 

best method is to have it in rear pocket of jeans face out while crawling under your car on a gravel driveway, this soften its up and cracks it,
later leave under your Toyota while working on radiator and carelessly drop a steel mallet off the engine block through the engine bay and onto the phone on the ground. this will help to finished the job. nice little Moto phone too before i got my hands on it.

 

10-24UNC X.5 LONG, PAN HEAD, PHILLIPS DRIVE. Course thread being the important factor to note.

 

The screw in the photo is actually pozidrive, not phillps. The easy way to tell is the pozi has the little hash marks at 45 degrees to the slots, a phillips will not have those.

They do take different screwdrivers, a phillips is designed to slip out, a pozi is designed to grip.

 

You are correct! The screw thread and length is what I was really addressing to help him solve his issue. If you have a pozi drive screwdriver and screw handy, fair enough. The pozi drive was created to accept a phillips screwdriver also. Phillips are readily available at any hardware store in the US and fit in the counterbore shown as would a "sq drive", "hex drive" even slotted. Slippage may be a concern when tightening or loosening with the seat in the car but if it was out and I needed to get it done I find a phillips in me screw collection, put it in there and call it a day. Thanks for your input, it's truly appreciated.

 

I hate Phillips, so I bought a complete set of pozi screwdrivers. Most of the screws on Jaguars are pozi, so it makes sense to have the right tools. I've been able to extract a screw with a pozi screwdriver that some previous ham fished mechanic has rounded off with a phillips driver.

 

Let’s not hate lol. But again you are correct!!

The screws in the UK in the 70’s were mostly slotted. Phillips was well established here in US for standard automated machines. When Phillips developed the improved pozidrive it was easier for Europe to standardize their automated factories with pozidrive. Still rare here, torx drive is more common.



Like I said he cared about thread size, head profile and length. The question was open and I closed it. What is ham fish? 🐠

 

Oops, a typo. Although a ham fish could be interesting couldn't it?

 

The human brain is an Amazing and Marvelous thing, doncha think?
I read that and immediately Knew, without even thinking about it, that it was a typo for Ham Fisted mechanic, but ONLY because I'm familiar with that term.
I'm probably not the only one!
Especially not the only Mercan to just gloss over the typo and catch the meaning.

Never knew, kind of the same as me being cack-handed or clumsy-handed as they used to call us left-handed folks 🫷🙂

 

this might explain why i have been ritually stripping certan large screws head over the years

 

If that’s the case, this will have been well worthwhile 😀 Like was mentioned by Jagboi64, it makes sense to have the right tools 🙂 There in NZ also readily available. Love all your photos btw, cheers

 

After years of working on British bikes, a quick glance at the side covers is all it takes to see if someone's been using the wrong screwdriver.


Here's one for ya...

Get ahold of a medium-size phillips screw (a #2 works fine) and screwdriver, and the same but in Pozi equivalent.

Hold phillips screwdriver pointing upward, then locate said screw into hex on driver and shake......boing! - it immediately falls to the floor.

Now, do the same with the Pozi set-up....it ain't going anywhere.

You now know why the Pozi design is VASTLY superior to the phillips. The Pozidrive screwdrivers also have a hex shank section abutting the handle...this is to allow one to augment the amount of torque you can apply, compared to just using your hand - the screwdriver tip will NOT rotate out of the screw's broach like a phillips does.

 

Neither of them can compare to Robertson, that is great screw head design. Alas, not seen in automotive fasteners; probably because it was a Canadian invention.

 

I like HamFished!
