Donut Style Masking Discs also known as donut style masking dots are designed for electronic manufacturing and are primarily used during solder wave process.

Donut Style Masking Discs are made of 7.3 mil crepe paper and can withstand temperature up to 300°F/150°C. They are packaged in 3" core roll with 1000 discs/roll except for GNDD-1X2 which is packaged as 500 discs/roll.

Donut Style Masking Disc Applications: High temperature paint masking, masking of painted metal, plastic and rubber surfaces where staining could be a problem, high temperature holding and splicing applications, industrial bundling uses.

NOTE: First number of the description is internal diameter and second number is outer diameter. For example: 1/8"x1/4" means this discs has internal diameter of 1/8" and outer diameter of 1/4".
