FITTING INSTRUCTIONS
STEP 1
Insert bolt into
predrilled hole
with marker
pointing up.
STEP 2
Rotate bolt
a half turn.
STEP 3
Secure bolt
with supplied
flange nut.
**We strongly recommend the use of our safety gauges when installing these Blind Bolts
WARNING: DO NOT EXCEED MAXIMUM TORQUE SETTINGS. ENSURE
ANCHOR IS IN THE FULLY OPEN POSITION BEFORE APPLYING
TORQUE OR THE PIN WILL SHEAR.
Shear strength was determined across the threaded area. Should the shear
plane fall below the minimum fixing thickness (across the hollow section)
shear strength will be reduced and must be recalculated. Performance
data listed is the ultimate failure load. Sherex recommends an appropriate
factor of safety when incorporating the Blind Bolt products into your
application. Additional testing available upon request.
Sherex offers a wide range of standard sizes,
and as always, we welcome special sizes.

Safe, Quick and Easy installation
for hundreds of blind-sided
installation applications!
Construction
Railway
The anchor system was used to tie mast climber
work platforms into tubular steel, making onsite
welding unnecessary. Blind Bolts therefore were
faster and easier to install, saving time and money.
Scaffolding
Blind Bolts have achieved certified acceptance as a
high-performance fixing solution for installing AWS
units onto steel railroad ties.
Marinas
Blind Bolts being used for holding critical masonry,
and scaffolding.
Blind Bolts are ideal for many marine fixing applications
including harbors, mooring points, etc...
Blind Bolts save both
time and expense!
