Supreme Wall Screw
Synthetic Rubber-Coated Wall Screw
DOES NOT NEED A WALL PLUG
Drive Supreme Wall Screw Directly into Hole in Wall.
Saves Time, Labour & Costs for Trade / DIY
10 times stronger than Wall Plugs and Wall Bolts
UK PATENT No: GB2443131 International PCT No. PCT/GB/2008/000895
How It Works:
When screwed in the rubber coating exerts an expansive rubber grip on the hole inner surfaces.
Each thread grips with 360 barbs; so 10 threads grips with 3600 barbs (compared with a Wall Plug max 10)
This is why Anchor Load Tests proved Supreme Wall Screws are 10 times stronger than the same sized screw used with a Wall Plug.
Drawbacks of Wall Plugs and Wall Inserts:
Even popular successful wall fixing Companies, concede (through statements in successive patents) that Wall Plugs are beset with drawbacks.
Some Wall Plug drawbacks are listed below:-
a. Hole too deep, plug pushes too far in, fixing screw fails to engage.
b. Solution – use plug with rim! – New drawback, rim proud, impedes flush fixing.
c. Fixing screw fits Article’s holes, but matching Wall plug too fat.
d. Wall plug need 2 masonry drill-bits, 1st for screw, 2nd for fatter Plug.
e. Wall plug being fatter, article’s holes cannot serve as drilling template.
f.. Heavier anchor loads require bulky, expensive, expansible Wall bolt.
g. Hammer fixings Inserts are too fat for article’s holes.
h. Wall plugs & Hammer fixings cannot be easily removed.
Solutions to above Drawbacks & Problems of Wall Plugs.
a. Hole too deep, no problem, TRICS™, thick resilient coating engages on entry.
b. Proud Rim! TRICS™ has no rim, giving inherent flush fixing always.
c. TRICS™ screw & resilient coating both fit Article’s holes.
d. Only one size drill (supplied) needed when using TRICS™.
e. With TRICS™ article’s holes can be used as drilling template.
f. Light & heavy anchoring loads – TRICS™ cater for all.
g. TRICS™ work as hammer fixings and fit article’s holes.
h. TRICS™ screwed in or hammer fixed can be unscrewed.
Drawbacks of Dry Wall Concrete Screws:
These self tapping un-coated tapered tip screws are suitable for light loads only, as
masonry, although strong in compression, is weak and disintegrates in tension & shear.
Solution – TRICS™ use expansive compression to obtain anchorage in walls.
Proposed Industry Standards for Supreme Wall Screws
Screw OD is uncoated thread Outside Diameter.
Actual Hole Diameter is usually larger than drill diameter.
Cordless Screwdrivers – Black & Decker, Bosch & Mac are recommended.
Maximum Loads are from Anchor Load Tests.
