Gundlach 1/8″ x 1-1/8″ Aluminum Drives (1 lb. jar)

Description

Engineered for securing various types of metal trim and tackless strip, this product performs exceptionally well on cement, terrazzo, marble, slate, or any masonry surface. The square drive’s four corners engage the walls of the undersized round hole with remarkable force, delivering holding power far beyond what’s needed for secure fastening. Available in six popular sizes, it comes in 1 lb. jars or cost-efficient 25 lb. bulk boxes.

Flat head style measures 1/8″ in diameter and 1-1/8″ in length, requiring a 1/8″ x 1-1/4″ hole for proper installation.
