Introducing The Gypfast Compression Screw
Standard screws are used for fixing Gypfast strip components at the edges of plasterboard sheets, however a special collared Gypfast screw has been developed for fixing directly into boards and is used to provide support to the centre of plasterboard sheets.
Because the collar rotates independently of the screw, it stops turning as it enters the plasterboard and is effectively"pulled" into the the plasterboard, unlike the traditional screw which has a tendency to chew up the surface of the plasterboard as it turns against it.
Plasterboard nails provide an even less secure and satisfactory fixing than the traditional screw, often resulting in damage to the surface of the board from hammer blows, bending over as they are driven in and pulling out over time due to thermal movement/vibration etc.
The gentle convex taper of the collar of the Gypfast screw tends to draw the external paper lining of the plasterboard into the hole, creating a funnel shape in the paper lining which compresses and helps contain the gypsum
The Bottom flange of the collar is designed to grip the innermost paper lining of the plasterboard, sandwiching it against the timber surface of the plasterboard (e.g. when using an adjustable clutch on a power driver).
Because of the increased load bearing surface area and increased integrity of the Gypfast screw fixing, boards can be fixed more securely, using fewer fixings than when using traditional methods, resulting in increased work rates. Back to top of page
Advantages
Some of the main advantages of the Gypfast compression screw a given below.
Cost Effective
Your costs are reduced as less of the Gypfast Compression scews are needed to support each individual plasterboad. Back to top of page
Time Efficient
The time taken to secure a plasterboard when using the Gypfast Compression screw is almost half that of conventional screws. Back to top of page
Stronger Binding
Because of the increased load bearing surface area and increased integrity of the Gypfast screw fixing, boards can be fixed more securely, using fewer fixings than when using traditional methods, resulting in increased work rates. Back to top of page
Less Screws
Because of the increased load bearing surface area and increased integrity of the Gypfast screw, less screws are needed per sheet of plasterboard. Back to top of page
