Exceeded my expectations
They all looked like machine screws. good thing
great as ususal.
Excellent screws and they were delivered FAST !
This product really screwed my airplane!
routine hardware order, in this case for an item that I skipped on the previous order. This order very small and I’m sure a pain to full fill. Thanks for great service on even this order.
As expected.
Q&A
Yes, they are measured from the bottom of the head to the end of the screw, the threaded portion.
No, it is a standard 4-40 thread.
Regarding Thread Sizes
Coarse Thread: 6-32, 8-32, 10-24, 1/4-20
Fine Thread: 6-40, 8-36, 10-32, 1/4-28
The first number is the size, or diameter, and the dash number is the thread count per inch. A #4 screw is .112" diameter.
You may want to consult with your A&P for more details of which would be better for your application. We suggest using the hardware recommended in the aircraft parts and maintenance manuals.
