2. The strength of sheetrock
relies on maintaining the
Three-Point Bond
of the components shown:
Sheetrock Structure
A - Face paper
B - Gypsum
C - Back Paper
Conventional Installation methods can’t accomplish this.
A. Face Paper
B. Gypsum
C. Back Paper
4. Typical Installation Problems (Cont’d)
Screws:
the face paper is cut
due to driving the screw
too deeply or is torn
from friction between
the paper and the
rotating screw head.
5. Typical Installation Problems (Cont’d)
Sharp edges on
rotating screws can
result in lacerated
fingers, resulting in
lost time.
6. Solution To Installation Problems
The shoulder on the Pre-Set limits nails & screws to a
constant depth, thereby limiting fracture of gypsum and
avoiding cut face paper.
A Small Innovation With Huge Implications
7. The Pre-Set Device
• Material:
Polycarbonate
• Properties:
• High impact strength
• Temperature range –
40F to 212F
• Good dielectric
strength
• Inexpensive
9. Pre-Set Nails
• Friction between the Pre-Set and the face paper draws
the paper down in a smooth arc, maintaining the
paper’s structural integrity.
• Pre-Set minimizes fracture of gypsum.
10. Pre-Set Screws
• Face paper is not damaged by overdriving because of
positive stop provided by Pre-Set.
• No cut fingers because Pre-Set is stationary while
screw is rotating.
11. Finishing
Pre-Sets provide a
1/16” recess of the
screw or nail head
below the surface of
the sheetrock to
ensure an adequate
depression to receive
joint compound.
1/16”
12. Temporary Positioning of Sheetrock
• Sheetrock may be
positioned using the
Pre-Set but not driving it
home.
• As such, it allows the
choice of relocating the
piece or driving the
screw to depth.
13. Changing the Industry Standard
• Hand installation of nails and screws is time-
consuming, therefore expensive.
• Pre-Sets provide a bridge to the future of sheetrock
installation by enabling the use of pneumatic nailers.
18. Time Considerations
• If a plain screw misses
the stud, the screw will
still advance through
the sheetrock.
• A Pre-Set screw will
stop advancing when
the shoulder contacts
the sheetrock.
• Driving a nail (3 strokes)
• Driving a screw
• Nail gun
4 Seconds
4 Seconds
1 Second
(Nail & screw times include
accessing them from a pouch
or apron.)
21. Summary
• A Perfect Fit For Screw-Nail Fasteners
• Maintain 3-point bond of sheetrock
• Screw & nail heads all recessed 1/16”
• Provide most uniform contact with studs
• Greater load bearing capacity
• Fastest installation
• Lowest labor cost
Advantage of Pre-Sets over conventional nails & screws:
