Safety Information
Recommended Safe Load
Pullouts listed are average actual pullouts and should
be used as reference only for calculations of acceptable pullout and shear
values. Values are ultimate averages achieved under laboratory conditions and
apply to fasteners manufactured by Speedy Products, Inc. only. In the process of
doing engineering, design personnel should divide by the recommended safe load
average in accordance with industry requirements.
Steel Screws
Because of variations in the hardness of certain metals, it
should be noted that our self-drilling screws for steel will experience
different drill rates.
- 500 - 1,500 RPM is considered optimal drill speed.
- Residual drill chips should not be blue in color.
- Residual drill chips that are blue in color indicate that
the drill RPM level is too high.

Installation Instructions |
|
DST, DSTR, TEK 50, SWD, SWDR, SWT |
|
See Figures 1 through 4 and 11 through 14 of
detailed installation instructions for illustrations. |
- DST self-drills & self-taps into steel up to 3/16"
thick.
- DSTR self-drills & self-taps into steel up to 3/16"
thick and accepts retainer nut.
- TEK 50 - Self-drills & self- taps into steel up to
½" thick.
- SWD self-drills & self-taps through 3/16"
steel.
- SWDR self-drills & self-taps through 3/16"
steel and accepts retainer nut.
- SWT self-drills & self-taps through
½" steel.
|
Step 1: Insert the appropriate nut driver into a
⅜"
or ½"
portable drill:
- use #14 Nut Driver for DST, DSTR, TEK 50;
- use #14SW Nut Driver for SWD, SWDR, SWT.
Step 2: Insert the screw into the nut driver. Now
you are ready to install the screw.
Step 3: Position drill and begin installation:
- for installing DST, TEK 50, DSTR*, the drill
should be in a vertical position;
- for installing SWD, SWDR*, SWT, the drill
should be in a horizontal position at a right angle to the structural
member.
Step 4: When the nut driver spins freely on the cap
of the screw installation is complete.
Step 5: Screw is now ready to receive
¼",
⅜",
½"
or metric all-thread rod or bolt stock. |
