Versatile, high-performance category that can drill and tap holes in multiple applications and materials

JC Grand manufactures a wide range of self-drilling screw designs for indoor and outdoor construction applications and structural fixing.

• Drill their own hole and tap their own thread.

JC Grand self-drilling screws are specifically developed for various applications. They provide high pullout strength, shear strength and maximum thread engagement and positive fastening in both structural steel and timber constructions.

• Time saving

Assembly and on-site labor time is greatly reduced by eliminating the task of alignment or the need to pre-drill holes. Fastening operations in roofing, cladding and assembly can be completed in less time, often halving the time of the old conventional method.

• Easy to Use

Utilization of unskilled labor is another benefit due to the engineering design of this type of fastener, as selection of drill size and various tools are eliminated. The tradesman will also realize the benefits of speed and ease of installation.

• One operation

As the fastening is reduced to one operation, alignment problems are eliminated. It is more economical to use self-drilling screws than to drill, tap and fasten or nut and bolt in the traditional manner.
