Silicone Multi-Flange Plugs
Multi-Flange Plugs (VMFP's) are a great option when the priority is being able to mask as many different holes sizes with a small inventory of plugs. Perfect for small powder coaters and job shops, these plugs allow for masking holes from 0.109" up to 0.709" with just three different plug sizes. With regular tapered plugs, that would take up to 15 plugs or more. Multi-flange plugs have a progressively larger tapered flanges on them, so they can be used for masking chamfers in threaded holes, or for the first thread in threaded holes that tapered plugs can't.
Series: SFPP
Silicone Flanged Pull Plugs
Designed to keep the top or first thread clean during industrial finishing — when no powder, paint or anodizing is allowed. Eliminates rework by masking weld nuts and top threads in one step. 40-45 durometer Shore A silicone. These indispensable masking plugs reduce costs by speeding up the process of masking 82° and 90° countersinks. To use, insert 'tail' into thru-hole, then pull plug into place with flange resting on opposite side for first thread protection.
Series: VTMP
Silicone First Thread Masking Plugs with Handle
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.

Silicone Flange Caps
Reusable masking caps designed to protect studs, bolts, and surrounding circular areas during high-heat finishing processes. Ideal for masking studs or bolts and a circular area around them, typically for grounding area protection. Our silicone flange caps eliminate the need for secondary washers by masking the circular area around the bolt, saving labor time in powder coating and e-coating lines. Alternatively can be used as a plug: The area around a hole can then be masked by the flange. They have also been used successfully as an insulation for wire harnesses (by cutting off the rounded end).
