Silicone First Thread Masking Plugs with Handle

Series: VTMP

Silicone first-thread masking plugs with handle (600°F)

Masking plugs for SAE, UNC or metric threads where the first thread must also be masked. Ideal for powder coating, anodizing or other metal finishing. Viadon's Silicone First Thread Masking Plugs have a handle to make insertion and removal quick and easy in threaded blind holes.

These plugs are specifically designed for the most common thread sizes, and we carry the most popular ones from 6-32 & M4 through other common sizes like 1/4-20 and M10 even up to M20. The straight wall of the plug section stays firmly in place, sized specifically for internal thread dimension. The top flange neatly masks off the lead thread of a hole, for perfectly masked threaded holes every time.

Choose the ideal masking plugs for your needs with Viadon's handy cross-reference chart: Masking Plugs For Threaded Holes Chart.
