An Overview On Fastening Tools

Fasteners are basically devices that join two materials together. In many cases, these fasteners are not a permanent fix, although they are designed to last for quite a long time. You’ll need some type of fastening tool to attach a fastener, and the model you choose is dependent on the specific project you’re working on.

If a plumbing project is next on your list, you’ll need a cinch clamp tool. You need to make sure the fastening tool you select will work with the size clamp you’re using. For example, the IWISS PEX Cinch Clamp Fastening Tool is compatible with stainless steel clamps that measure 3/8-inch, 1/2-inch, 5/8-inch, 3/4-inch or 1-inch.

Make sure the fastening tool is comfortable and easy to use. The GDHXW PEX Stainless Crimping Cinch Fastening Tool has a longer handle with a rubber coating to reduce the amount of pressure needed to operate it. It also utilizes a ratchet design, which releases only when the cinch clamp tab has been pinched correctly.

Semi-automatic tools are excellent for attaching things like electrical boxes, wood boards and furring strips to materials like steel, masonry and concrete. It’s a good idea to look for a fastening tool that is lightweight, so you don’t have any trouble operating it for an extended period of time. You’ll also find models with silencing handles for quieter operation.

Review the construction of the semi-automatic fastening tool. A unit made from metal is more durable and one that has the ability to drive ten pins from one strip of loads reduces the amount of time you have to spend reloading the machine. The Ramset COBIII Cobra Fastening Tool offers all this, as well as a padded recoil-absorbing handle.

Check if there are any extras that come with your fastening tool. The Hilti DX 2 Powder-Actuated Fastening Tool provides customers with a host of additional benefits, including lubricant, a spares pack, a cleaning kit and a storage case.

The Fastening Tool Buying Guide

  • Some reviewers report that certain fastening tools used to crimp large clamps on PEX pipes cause wrist pain. If you can’t try the tool out before you buy, you’ll want to read the reviews to make sure you are purchasing a model that is comfortable to operate.
  • It’s important to keep your fastening tools organized. Not only will you save time when you need to use them, but you’ll also reduce the risk of losing the tools altogether. If the fastening tool didn’t come with a storage case, you may want to purchase one separately. You could also opt to designate a drawer within your tool chest for this type of tool. Labeling the drawer is always a good idea. Another solution is to purchase a tool bag and use the outer pockets to hold your fastening tools.
  • Should you get any dirt or grease on your fastening tool, you can wipe the tool down with a little dish soap and water. Use a grease-fighting detergent but don’t place any semi-automatic models directly under running water. You simply want to wipe down the outer surface. Follow that up by drying the tool off with a lint-free cloth.
  • The price you pay for a fastening tool is dependent upon whether the tool is designed to be used manually or not. For example, the IWISS PEX Cinch Clamp Fastening Tool and the GDHXW PEX Stainless Crimping Cinch Fastening Tool are the most affordable fastening tools, as they must be operated by hand. You’ll pay much more for the Hilti DX 2 Powder-Actuated Fastening Tool or the Ramset COBIII Cobra Fastening Tool, as these models are semi-automatic and do a great deal of the work for you.
