• FOR STRONG, RAPID, RELIABLE, NONPROGRESSIVE RAIL JOINERY •
Used on
: stair rails, KD furniture, store fixtures, and special assemblies.
These Gear Head Screws are operated from 90°, replacing hanger bolts, ball nuts, etc.
They are easier to install, easier and quicker to operate and tighten, and perhaps most importantly,
they permit
nonprogressive assembly.
Sections being added as above are slid into place
in their own length
- nonprogressively -
because the Gear
Head Screw is retractable. (
See TDS/GHS-221- 2 & 3
)
Here the
Gear Head Screw
and wood insert are being
tightened with the installation tool.
Tool engagement and tightening is uninterrupted,
therefore, rail joining is accomplished rapidly.
A ratchet wrench can be used for tightening.
The special design of the wood insert achieves a strong
positive hold -
even in end grain
.
These 90° operated gear head screws are easy to install,
easy to tighten, and you can put your stair rail sections in
place nonprogressively (in their own length), in either
straight butt joints or angular joints, because the G.H.
Screws can be retracted flush when assembling.
(
See TDS/GHS-221-3
).
Stair rail joints are an ideal application for the gear head screw.
Many configurations can be assembled
nonprogressively
.
• Gear Head Screws can be retracted flush for
nonprogressive assembling/disassembling.
• Strong, tight joints are made.
• Preparation of joined members is simple.
• Easy installation.
•
Operated from 90°.
• Quick, uninterrupted operation is accomplished
when turning the G.H. Screw.
• Close quarter joints can be made.
• Economical due to time saving.
• Easier to use than hanger bolts, etc..
• Geared tool & G.H. screw tooth engagement is positive.
• A ratchet wrench or ‘spin-tight’ can be used to tighten the
Gear Head Screw.
• Facilitates angular component assemblies previously
not feasible.
• Easily removed if required.
