Quality upholstery tacks or nails. We are often asked which tack to use for which material and chair or sofa frame. The answer is to use the smallest tack suitable for the job, too small and your work may not hold or may tear, too large and your frame may be damaged. As a distinction, improved tacks have larger heads than fine. Typically purchased in 200 Gram packets, these tacks are also available in 50 Gram handy packs, and 1 Kilo packs for extensive use.
As a guide for use:
6mm Fine - Very fine work with delicate fabrics.
