To tighten down a BoxBolt, an installer must typically use 2 wrenches to install one bolt – one to hold the outer sleeve stationary, and one to turn the inner bolt.

A Faster Way with BoxSok

The BoxSok adds simplicity to the installation process.  Attached to a regular socket wrench (air powered makes this a snap), it takes the place of both wrenches.  The BoxSok has an outer piece that will hold the sleeve of the BoxBolt stationary, while an inner piece turns the bolt.  This makes what would have been a 4 minute job (per bolt) into a 30 second job. 

A "good" reason to buy an "expensive" socket

1. Let’s say that the average installer costs $30.00 per hour to have on site (this usually is a very low estimate)
2. With 2 wrenches, this installer will take approximately 4 min. per bolt to perform the installation, whereas it will take 30 seconds with the BoxSok.
3. Let’s also say that you are installing 1000 bolts
4. If you are saving 3 ½ minutes per bolt, this is equal to over 58 hours of labor.
5. Going back to the original amount that our installer is being paid, this equals $1,740.00 in savings. 

Other BoxSok benefits consist of:

1. Less fatigue on the installer
2. You won’t hold up other aspects of a job while waiting for the bolts to be installed
3. You will be able to get off of the jobsite faster

Pipe is not always easy to measure.  We have tried to make it a little simpler by providing a printable pipe chart.  To use this chart, click on the image (a full size version will appear).  Set your printer to landscape mode and print the graphic full size.  It’s important to make sure that your printer is not scaling the image to make it fit on the paper — scaling the image will make measurement inaccurate.

Recommended Set Screw Torque Value 19 ft/lbs
Slip Load Steel pipe/tube = 1,300 lbs, safety factor of 2:1
Slip Load Alum. Pipe/tube = 1,100 lbs, safety factor of 2:1

Exhaustive tests on samples of standard size 7 Kee Klamp fittings were performed by an independent research laboratory. The purpose of the test was to evaluate the use of either standard set screws or self-locking set screws.

Test Arrangement

A “Tee” section test assembly was made using three 12 ft. lengths of galvanized size 7 standard pipe held together by a three socket tee fitting (Type 25-7). The vertical leg of the test assembly was supported in a standard railing flange (Type 62-7). The completed assembly was then rigidly attached to the vibration table.

The test assembly was initially assembled using standard set screws and tested in this configuration. The standard set screws were then replaced with the self-locking screws and the tests repeated.

Test Procedure

The test was conducted on a Ling 667 kg Electromagnetic vibration table. The table was programmed to perform a resonance search between 25 and 350 Hz. and resonant frequencies were recorded and shown in Table 20.

During the resonance search amplification factors, Q, were measured at each resonant frequency, the point of reference being the end of one horizontal pipe. The table was then held at one of the resonant frequencies, set in motion with a controlled acceleration level of 4g, and ran for a period of six hours. This was repeated for three more resonant
frequencies in descending order of “Q” factor.

Table 20: Test results

During the twenty-four hours of vibration at the four resonant frequencies above no signs of loosening with either type of attachment screw occurred.
