Direct Fastening

ramset-sp178-bw.png

Fastening 2x material to steel is fast and easy with a Ramset, Hilti or other powder actauted tool as long as you keep a few things in mind.  First off, make sure your steel is thick enough to fasten to with a powder actuated tool (P.A.T.).  A good rule of thumb is if the steel is at least as thick as the shank of the pin, you should be good to go.  The pin we recommened for fastening 2x material to steel with a P.A.T. tool is the Ramset SP178 which has a shank diameter of .150 on the thinner part of the shank (about 5/32″).  The steel can be much thicker even 3/4″.  The pin will only go in about 1/2″ if your tool has enough power.  You don’t need to penetrate the steel for full holding power.  Obviously you would want to penetrate thinner steel.  Click here if you would like to see performance in steel.  

You will likely need you highest power level, but for safety sake, start with lower power and work your way up.  As long as we are on safety, any time you fire your P.A.T. keep your safety glasse on and you will for sure want hearing protection when firing to steel.  If fastening 2x to steel on a regular basis, I would recommend a tool like the Ramset XT540 or the Simpson PTP27.  Both tools have a well built front end which will hold up to heavy hit of shooting to steel.

If you are looking for a fast way to fasten 2x material to steel using a Hilti, Ramset or other powder actuated tool really does work well.  Keep in mind the requirements mentioned above as well as taking the proper safety precautions and you will be pleasantly suprprised how well it works.  You can find the Ramset SP178 pin for fastening 2x material to steel here.

j-hooks

Basic J-Hooks.  For years we had requests for j hooks from our customers.  Finally one of our suppliers a produced a generic UL listed j hook in the standard sizes.  Available in 3/4″, 1-5/16″, 2″ and 4″ sizes. These continue to be one of our best sellers.  They are available in a variety of configurations to fit your install.  They have a great price point and as a day in day out cable support, they will save you money.  While most of our customers are using hook and loop to secure the bundles, a plastic retainer is available for the 1-5/16″ and 2″ sizes.


The Arlington Loop.  The Arlington Loop is a plastic hanger approved for use in air handling spaces.  We were one of the first distributors in the midwest to champion the loop.  The Loop is available in a 2″, 2-1/2″ and 5″ size.  Cost and flexibility is one of the reasons why the Arlington Loop has been a big mover for us. We make a few different custom versions including one with a hammer on clamp for flanges and beams as well as one with a multi clip or bat wing for grabbing on to grid wire.  We do a lot with nation wide rollout projects that we build the hammer on version by the pallet.  Learn more about the Arlington Loop here.


Pre-tied Ceiling Clips.  This is another product a customer begged us to make for him.  He needed 300 to suspend a cable run.  Well we gave in and now we tie thousands upon thousands!  Many are shooting up a grid wire and then twisting on a j-hook or Arlington Loop.  Some are adding a second cable hanger up the grid with a bat wing or multi clip.  Shipping can be a challenge.  We encourage you to buy in packs of 200 as the shipping is virtually the same.  A second option for you is to buy one of our hand wire twisters and make what you need as you go.  A word of caution.  If you are tying on clips for your Ramset or Hilti tool, make sure you use a quality clip like the Ramset SPC78 or SPC114 for a better “stick” rate.  You can find them here.

What Is Direct Fastening Anyway? Direct fastening is the process of forcing a stud or nail into concrete and steel.  It is direct in that it eliminates any pre-drilling or tightening to expand an anchor.  The most common form of direct fastening still has to be forcing a pin into concrete to fasten 2x material or metal studs for drywall. 



I have sold and serviced many powder actuated tools over the last 20 years including the Hilti DX350 and the clone versions of the tool from many different manufacturers.  They are just such a solid tool with many different uses.   Here are a few points to help you find a good deal on a good used Hilti DX350.  Don’t just accept the statement that the tool fires or works well.  I have seen tools advertised as working well when they were obviously missing parts in the photos. The tool will handle pins from 1/2″ to 2-1/2″ with washer making it a perfect choice for all around general contractors.  As it can be mounted to an extension, it is also a great choice for electricians, ceiling contractors and data comm/low voltage work.  The only use I don’t like the tool for is tasks that are prone to over driving the tool like  putting foam to concrete.  Check us out for pins and loads for the Hilti DX-350.

A Hilti DX350 tool should not just fire, it should fire solidly and advance one load each time you cycle the tool.  The most common thing a used tool may need is a piston or driver.  The piston or driver is what forces the pin into the concrete.  They are a wear part and so they chip up and can even break.  An aftermarket piston to fit the Hilti DX350 goes for around $30.  The driver is easy to replace.  If the tool isn’t advancing the load advance isn’t expensive, but it is a little more tricky to replace.   The little “C” clip that holds the front barrel together can get bent up from time to time.  Again this is a wear part, easy to replace and many of the tools have extra packed along with the tool.  Stay a way for a tool that has cracks or breaks on barrel or fastener guide.  If the tool fires and advances but make just a “poof” sound, almost like a bad load, it is likely the return pawl that reset the piston is warn.  Easy to replace but figure another $20 or so to fix.

When you are looking for a used Hilti DX350 tool you will find clone tools from Ramset, most notably the Cobra tool.  The Cobra is a great tool, but stay away from the Cobra Plus tools, many of the parts are not available.  As for prices, I have seen them all over the board but many good tools can be had for $100-$150 or so.  If you shop around you may find a tool with loads and pins to fit your application.  FYI the tool is a .27 caliber strip tool.  Loads are readily available at most big box stores.  The loads are color coded, going from the lowest, GREEN, YELLOW and then RED.  Start with the lowest power level and work up until you pin sets to correct depth.  Ramset, Simpson and Powers loads will work in the DX350 if they are .27 caliber strips.
