.625" Fastener Grade Tip

Great for butter grades, Fastener grade mastics. Often my second choice for sealing fasteners if the .47 tip feels to slow or I am having to push too hard. Take the tip out to draw the material, screw it back in (4-5 turns) and you are ready to seal some leaky fasteners. If the material you are using feels too messy with this tip, consider trying our smaller .47" tip. If the material feels too slow coming out of this tip, try out 1.0" Seam sealer tip (yes even if you are still trying to seal screws) Show more
