MDF-Tite MDF Screws 3.9 x 40mm 200 Pack (40376)

Designed to meet the latest developments in MDF board. Tri-Lock threadform and shank incorporates the benefits of a single coarse thread with a twin thread start on the same screw. Spiral point breaks through the hard, dense surface, allowing the twin thread to engage. The twin thread is reduced to a single coarse thread, enabling high pull-out retention. Underhead ribs for self-countersinking. Zinc and yellow-passivated.

Will these screw into mdf end grain and not spit the mdf?

Asked by: doeruper
Hello It depends on the thickness of the MDF. If in doubt, drill a 2mm pilot hole. Regards Tite-Fix

Why do these blow out the MDF sides

Not sure how a anyone makes these work. They blow out the sides of MDF. I normally use spax MDF fixings which have a much thinner shaft. Really hard to remove but don't damage the Sides
Asked by: TSJTimber
If you are driving close to the edge drillign a pilot hole will eliminate the problem.

Is it best to drill a pilot hole for the MDF-TITE screw 3.9 x 40mm ?

Asked by: BLOSSOMVILLE
You shouldn't need a pilot hole for MDF-Tite however, it depends on the application.
