    Answer This Question

    A:  I have used these screws in many different materials with no real issues. Particle board is known for chipping and fasteners coming loose. The pine strips are a good idea and will hold better than screwing the slides to the cabinets directly. The best way would be if the cabinets are not installed yet and you screwed the pine strips to the box from the outside of box and into wood strips. ....................... Hope this helps

    Q:Will this work to hold melamine cabinets boxes and drawers
    by|Aug 30, 2018

    Answer This Question

    A:  Probably good for your (1/2") drawer sides, but would consider a courser thread and thicker #10 for the melamine cabinet box (3/4"). HD sells particle board screws or match up to a similar Spax construction screw. Would still recommend a predrilled starter to prevent expanding and weakening the particle board edge.

    by|Jan 9, 2019

      A:  yes

      by|Oct 4, 2018

        A:  I don't know the official answer to your question, but I screwed it into, what I consider to be, oriented strand board (OSB) and it held just fine. I would consider the particleboard core of melamine to be somewhere between MDF and OSB, so I would try it.

        by|Sep 7, 2018

          A:  The SPAX MDF screw is suited and designed for MDF applications. Melamine is usually used as a coating for MDF so this screw should be ideal. Thank you for being a SPAX customer!

            Q:I am attempting to install hooks for towels into 3/4” mdf. Would these screws work for that purpose and hold the hooks strongly in place?
            by|May 21, 2018
            5 Answers
            Answer This Question

            A:  Yes. Although the head of the screw is small. Other spax interior screws may be better as the screw head is larger. Be careful driving other screws near the edge of the mdf as this particular screw is meant to be able to drive near the edge of an mdf sheet without stripping the mdf.

            by|Oct 8, 2019

              A:  They should do just fine unless you have a lot of 50# towels ;-). You will want to pre-drill each hole though. MDF is tough to screw into without pilot holes. One other thing you should take note of is because MDF is so dense and has no compression space, you will get a little bump of material around the pilot hole when the screws are driven in. A bigger bump if pilot holes are not used. You can mitigate this by using a small countersink bit after the holes are drilled. This will create the space needed to allow the MDF to expand into the countershink area. Note that the screws have small raised lines that run from the base to the top of the screw head. These are there to prevent the screw from twisting once it has been driven into the wood/MDF etc. They will scratch the finish on the towel hanger if you drive them in all the way. Should that be the case, you can 'fix' it by putting a small drop of matching paint on each screw and using it to cover any marks left when the screw was driven in.

              A:  Think would be better using screw with a course screw thread for grip and less risk of pull out. Also want a screw with a full screw or clear shank not much deeper than your fixture piece.

              by|Jan 8, 2019

                A:  It’s probably a better idea to use Everbilt Toggle Bolts for an application that does not hit a stud. The toggle bolts have sizes/strength for different weight requirements. They are easy to install and work like a charm!

                by|May 22, 2018

                  A:  Yes ...... they should work fine for this purpose as long as you do not plan on putting heavier objects on hooks.

                  I use this product to hold together birch plywood that was slightly larger than 1/4 and slightly less than 1/2. i can say that they work just as advertised. It will not split wood even if you get dangerously close to the edge. These are quality screws that grab and will not split your wood. The secret is in the tip of the screw according to the spax rep i spoke with at home depot... I love these screws!!!!

                    It's is exactly what I needed to build a shoe rack using MDF material. After pre-drilling and applying wood glue the SPAX screw just secured the joints nice and tight. I would highly recommend SPAX it's a perfectly designed and engineered to tackle on woodwork using MDF or particle board material.

                    They're a great product I really didn't have to pre drill any holes either. They didn't split the wood and they counter sunk Perfectly. They are very secure they really pull the pieces together.
