Harbor Freight parallel clamps (compared with Jet and Irwin)


  • Harbor Freight parallel clamps (compared with Jet and Irwin)

    I own a variety of clamps, and only recently started using parallel clamps. I own a few from Irwin and Jet, and I tried the Bessey clamps in the store. I recently got a sale flier from HF with a ridiculously cheap price on their parallels, so I had to try them.

    Overall impression: Better than the Irwin and Bessey clamps, not quite as good as the Jets but 1/4 the price.

    All of these clamps (Irwin/Jet/HF) have nice big handles. The Jets are hard plastic with three rubber strips for good grip. The Irwins are all rubber, and the HF are solid aluminum with a grained finish. That sounds less comfortable, but it's not, and gives excellent grip. All of the handles are just fine for comfort and power.

    The Irwin has the largest jaw face, and the HF the smallest. All of them have smooth jaws that stay parallel.

    The mechanism on the Irwin is the least desirable. It has a locked and a loose setting, but nothing in between. In the loose setting the head will slide with little provocation, making it very hard to pre-set them and then use them one-handed while holding a work piece. The Jet clamps have a release trigger, so they are locked in place until you pull the trigger. This is pretty easy to use one-handed. The HF has locked and loose settings as well as an in-between setting where you can move it with direct pressure but the head doesn't just slide around on its own. This is very easy to use one-handed. The Jet and HF clamps have teeth on the bar to lock the position, while the Irwin does not, which is why this works the way it does.

    The bar on the Jet is shiny and slippery, resists glue. The others are rough and glue does stick more easily. The Jets have inch markings on the bar, which is very useful. All of the bars are much stronger than needed for any amount of hand pressure you can apply, so bending is not an issue.

    If I was stocking up today, I would buy a few Jets as my main clamps and HF for my backups. The Irwins are inferior to the HF clamps in most ways, so I wouldn't buy them again. The Jet four-clamp cabinet kit is a good start, with two clamps of two sizes and four of the square-up clamp holders included, as well as a set of bench dogs.

      I received a set as a gift, cursed them when used as invariably they pinched the web of my hand (btwn thumb and pointer finger). Found myself usually needing 2 hands to operate. unlike my much older, still working "Quik Grip" from Vise-Grip.

      Worse yet, not 1 but 2 broke when hand tightening. The ends snapped off w/ such force I didn't see where they landed. Very close to loosing an eye. BTW I shop HF often but mostly for disposable goods... bits, blades, gloves, etc. Hope to avoid someone a costly bargain.
      This review was for the Parallel Clamp, not the clamp / spreaders (Quick Clamp clones) that it appears you are talking about.

      I wouldn't completely write off HF clamps. I have a large selection of the HF bar clamps and they are every bit as good, and in some features, better than Jorgensens...

      I had heard that there might be some problems with the HF "quickclamps" but your post is the first I've seen regarding failure of the HF "parallel clamps" (if indeed that is what you are reporting).
      I can confirm that the HF "quick clamps" are a POS!! I got two and with my emmense Hulk like strength (not) was able to break them with just my hands. I wasnt even squeezing as hard as I would normally with my Irwins. The body basically has zero structural integrity and fails at all the screw where the side plate joins which essentially holds it all together. I drilled out the failed joints and replaced with bolts. They now only get used for light "holding" applications as a clamp they are NOT!

      An update on these after a year of ownership and a few projects. They are holding up like new. I am still just as happy with them as I am with my Jet and Irwin parallel clamps. If HF made these in a longer size, I'd buy a few.

      Also in general I'm happy to have discovered the concept of parallel clamps. So much better for furniture-making than your standard basic clamps.

  • A review of the Kreg Precision Trak & Stop Kit
    by twistsol

    I built my miter station last summer and used the Kreg Precision Trak & Stop Kit. The kit was just the starting point. 8 feet of track and a single flip stop didn’t meet my needs since I was building a miter station the width of my shop, nearly 24 feet. I added four 48” pieces of top track and three additional swing stops so I could have two left and two right. Finally, I added metric rules to the top. Total cost breakdown is as follows

  • Review of VIX-type Self Centering drill bits
    by LCHIEN
    I have always had trouble mounting small hardware on small wood boxes, with the hasps and hinges always looking slightly off perfectly square - particularly a problem with flat head screws and countersunk hardware which aligns the hardware to the hole location and centers on the hole.

    I'm talking small wood screws. I place and mark the hardware carefully and mark the center of the hole with a sharp awl.
    The problem comes about with small bits like 1/16 and 5/64 and 3/32"...

  • Grizzly Overarm Blade Guard review.
    by twistsol
    Since my new shop is in the basement, dust collection is a bit more important than when I had my own building and could do as I pleased in the shop. With that in mind, I upgraded the dust collection on my table saw. I purchased the Grizzly Overarm Blade Guard to use with the saw.

    First impressions were that this is an extremely solid and well built unit. It's made mostly of steel and connects to a 4" DC hose. There were a number of issues getting it set up and installed, and a...

  • Kreg KMA 3220 5mm Shelf Pin Jig
    by twistsol

    I decided to look for the rock bottom cheapest 32mm drilling system available that would let let me create real 5mm holes spaced 32mm apart, that was easy to use, and didn’t require a bunch of setup time. I’m really surprised at how much I like this little Keg jig especially when you consider the price of $34.99, and it has everything included. There were a couple of jigs cheaper but you needed to buy a self-centering 5mm bit to go along with them so they would...

    Here's a tool I found useful for marking. Accutrax pencil blade marking knife.

    I have one I've been using on and off for a while. Its a fine pencil lead in the shape of a utility blade that can be installed in any utility knife handle and used with a straight edge, combination square, saddle square etc. to mark easily seen, fine lines on wood..

    Here's mine. I have not broken it, it seems to be quite sturdy. The sharp edge lasts a long time. I'm still on the...

  • Saddle squares
    by LCHIEN
    Hey, I'm sharing one of my favorite tools. A Veritas Saddle Square. Actually I have two in different sizes. This is the large size for marking 2x4 and 4x4 (shown on 4x4 here). One of those tools that makes woodworking a pleasure.

    They're great for continuing lines from side to side. And even side to opposite side.
    Works really well when the board has a rounded edge or some wane where the edge is not really sharp and square but the two adjacent faces are square to...
