Description
The HECO-UFIX® is a part-threaded screw with a special shaped spade-like drilling point. It has all the properties required for working with medium-density fibreboard: predrilling effect and pinpoint-accurate insertion, reduced splitting and low driving torque. Another advantage is that the HECO-UFIX® MDF screw has a newly developed drive: the HECO-Drive, a perfectly coordinated system between drive in the screw and the special HD bit. The screws stick-fit into the bit and do not wobble. This allows for one-handed operation without any problems and exact screw guidance. However, the screw is also compatible with any standard T-Drive bit.
BENEFITS
Possible to work close to the edge and axis
Enlargement of insertion hole due to ribs on the point of the screw; thus reducing the splitting and bulging of the MDF
ADVANTAGES
Perfectly coordinated HECO-Drive and drive with stick-fit effect; the bit holds the screw securely without wobbling.
Exact, non-slip positioning on the surface of the material
Only one size of recess for the whole product range
