How to Choose a Masking Plug Size
A plug choice starts from measured geometry, then needs a test under the actual finishing process.
Start with measured dimensions
Capture the working diameter, depth and thread details from the actual part rather than a nominal drawing only.
Choose the plug geometry
Tapered, pull and flange styles solve different handling and face-masking problems.
Confirm by sampling
Validate fit, coverage and removal after the full process before releasing an approved size.
