Concrete contractors make forms, pour concrete and then hope to take the forms apart for future use. Concrete-covered nails are almost impossible to find, however, and over-pouring on a nailed-up form can make the form useless for future use. Screws hold your forms together better than nails and the MudHead cup and cap keep them visible and quickly removable by preventing concrete from getting to the screw head. The bright orange cap makes screws visible even if they're partially covered by concrete. Save time and money. Works with FastCap MudHead or PowerHead screws. Pack of 50. Made in USA.
