Hi,
I need some screws that are made to imperial size standard but do not know how to name it to look for on ebay or elswhere.
Length is with the head: 0.625" or also 0.73"
Width is 0.25 for the screw
Head is only 0.37" width and 0.125 high". Loot at the pictures.
The screw-thread is less tigth than what I found in EC...
How would you name it in USA or Great Britain please ?

Yeah looks like a torx fastener but no way to tell what size and if it has a pin in the middle it's the security version.

Thanks PRR, I can answer exactly tomorrow, but on the picture attached the 0.73" has a screw length of 0.6" (around 1.5 cm) . If I look at closer I would say around 8 or 9 threads / 1 cm.
@conanski (thanks) it is more classic I think : rigth angle, six facets, I want to change it because the screw-driver wasted the shape little by little... I can not change the bolt...
I come back with better datas and pictures tomorrow, that were screws used on a US loudspeaker... Boston Acoustics. NON existing anymore I believe.

Looks like plain old 1/4-20 socket head cap screw. Appox. 1/2" of thread, or maybe 5/8" is you measure .6"?
I count about 9 threads (1/2" length of thread) on a standard cad model for this screw size. Head diameter .375" x .25". Overall length .75". Hex key 3/16".

Thanks, I didn't know it was measured like that : so, yes, width is exactly 1/4, and around 15 "thread count" on the biggest, around 8 or 9 for the littliest 0.6" length...
Hey maybe Part Express, Solen, Meniscus ? Or closer in GB shop ?

Here's a link to the McMaster-Carr page just for reference. https://www.mcmaster.com/91251A539/

Still got a 35mm camera in the attic? Camera tripod mount screw/hole is always 1/4-20, at least here. I bet this goes back to Kodak folding cameras (or before). I've never seen an adapter for any other screw, or notes like "US market".
If it goes in most of a turn and then wants to jam, it is 1/4-28.

I’d say 10/24 socket head black oxideHi,

1/2” or maybe 5/8” would be my guess
The picture is fuzzy so I can't quite tell the exact shape. It may be a shadow by the head that makes it look taller than it really is. The following matters only if cosmetics and a close visual replacement is important. If the head is fairly round and tall, it could be a fillister head screw. If the head is shorter, it could be a variation of a pan head screw. To look at options available and obtain dimensions, https://www.mcmaster.com/screws/ is a good option.
Buy a Torx wrench instead?
That would be less trouble, or put standard Allen bolts in its place.
Take a look at the thread profile, UNC profile is different from BSW and Metric, the thread angle is different.
UNC is mostly in cars, though.
If it is a through hole, a smaller standard fastener with washers will work, put a nut at the other end. Use a longer one, of course.
