ASSY ^® - the innovation screw

1. RW^® drive and 2. RW^® recess: more power, fewer bit changes

• 2 bit sizes for the most common diameters
• Perfect fit between screw and bit
• Deep insertion of the bit
• No wobbling
• Precise positioning of the screw thanks to exact screw guidance
• Tight-fit recess without magnetic bit holder (screw is held by a bit clamp, enabling one-handed working)
• No slipping of the bit, even with maximum torque transmission
• Long service life of the bit
• No cam-out
• Combine the advantages of Phillips, Torx and AW drive
   

3. Milling pockets: countersink perfectly in all applications

• Optimum balance of joining and head countersinking
• Suitable for wood and fittings: braking effect on metal, milling effect in wood
• Perfect countersunk finish in coated chipboard
• Optimized number of milling pockets depending on the application
• Continuous 90° head geometry for a precise connection of metal and wood
   

4. Integrated milling shank

• The “auxiliary motor” that reduces the amount of force required when using partial-thread screws (from diameter = 5 mm, l = 70 mm)
• Little material destruction thanks to displacing and milling effect
• High breaking torque and low tightening torque: low risk of screw breakage, especially with long screws
• Spares all tools and accessories applied (bit/screwdriver) and reduced strain on wrists thanks to reduced amount of force required
• Minimized risk of injury from metal chips due to integration of the milling shank in the thread
• Reduced risk of splitting upon entrance of the shank
   

5. Asymmetrical high-performance thread: more efficiency and safety

• No over-tightening or stripping and anchoring at high feed
• Reinforced, asymmetrical thread flank geometry for higher power transmission in hardwoods
• Increased anchoring depth thanks to higher thread flanks
• Fast and fatigue-free working thanks to coarse thread of ASSY 4 steel screws
• Safe working thanks to single thread of ASSY 4 stainless steel and ASSYplus 4 screws
• Faster and easier to screw in than conventional chipboard screws
   

6. Tip with milling ribs: fast biting, reduced risk of splitting, less force required, smooth screwing in

For all ASSY^® 4 screws

• Smooth thread start ensures optimized piercing and fast biting of the screw
• Low risk of splitting thanks to the milling ribs with displacement effect especially when screwing in at edges
• Reduced screw-in force to be applied by minimizing the friction of the thread rotation
• Reduced abrasion of the corrosion protection layer on the thread
   

6. Drill tip: edge distances as with pre-drilled holes

For all ASSYplus 4 and ASSYplus VG 4 versions

• Minimal edge distances are possible to achieve edge distances as with pre-drilled holes and no risk of splitting thanks due to effective chip removal and adjusted bit edges

And especially for ASSYplus 4 screws with centring drill tip

• Precise positioning without slipping for screws with centring drill tip, even on hard surfaces thanks to centring pin
• Exact drilling process thanks to precise fiber separation by means of sharp cutting edges
