Welcome to the SFS intec Tutorial. During this demonstration we will demonstrate how to install the SDK fastener through a halter to a metal deck.
The demand for rapid installation and the need for secure fixing of metal sheets to the underlying structure can often cause problems such as over-driving into the structural metal, dangerously thinning the metal sheeting, and stripping the screw threads on the fasteners.
This leaves the halters very vulnerable to pull out from high winds, or unable to resist structural/thermal stress, and the failed fastener can reduce the integrity of the roofing system.
The unique SDK fastener has been designed by SFS intec to prevent the problems of overdriving and stripping out of the threads in the metal sheet/substrate when contractors are installing on site.
The SDK was developed specifically for Kal-zip to fasten their halter to the metal deck or top hat/purlin.
The special drive mechanism - the square drive peg - detaches when correct tightness has been reached.
Correctly position the halter onto the top hat/purlin or metal deck.
Then put the peg end of the fastener into the adapter in the drill nose. Once positioned in the clip, drive the fastener through the corner holes of the halter. When resistance of the screw builds up to the correct torque the square drive peg breaks off. This indicates that you have reached the optimum torque and the fastener is securely fixed.
The pegs are collected in the hopper of the adapter and do not fall onto the metal deck or vapour controlled lining (VCL) which could potentially be punctured or damaged.
Once the hopper is full, simply pull out the adapter and pour the pegs into a bucket or other container.
If required the fastener can be removed as there is an hexagonal head below the top of the fastener – simply turn over the front piece of the adapter and unscrew.
Thank you for watching the SFS intec Tutorial on the SDK fastener. We hope you found this demonstration useful and should you have any further questions please do not hesitate to contact our technical team on 0113 2085 578 or why not view other tutorials from the series.
