How to Screw into a Plastic Kayak

Do you want to attach accessories to your kayak ? Attaching screws to the kayak body might be what you need. However, this process requires steady hands and appropriate tools. Any little mistake will lead to a bad leakage. You must match the type of drill you use to the screws available. A silicon sealant will be the best to cover the screws completely.

A kayak spends most of the time in water; hence stainless screws will be appropriate. This type of screw is resistant to corrosion. Also, ensure the screws have a locking nut to prevent them from loosening. Moreover, deciding the position of the screws is an essential factor. This helps to ensure the screws don’t affect the balance of the kayak.

The procedure below will help you to screw into a plastic kayak

Equipment you will Need

  1. A drill and drill bit
  2. Stainless screws
  3. A marker pen
  4. The accessory you want to attach to the kayak
  5. Screwdriver

7 Steps to Screw into a Plastic Kayak

Step 1. Find the appropriate position to attach the accessory to your kayak. Professionals recommend attaching the accessory to the back of the kayak. Please consider the balance of the whole kayak first.

Step 2. Use the marker pen to mark the position of the first hole. Creating a mark will help you to handle the drill on the plastic.

Step 3. Fit the appropriate drill bit in the drill. The drill bit will depend on the size of the screws. A wrong drill bit can easily create a crack when screwing into the plastic.

Step 4. Now drill the first hole. Firmly hold the drill to prevent it from moving around. Also, ensure the hole does not go too deep into the plastic.

Step 5. Then take your accessory and set it on the first hole. Mark the remaining holes with the marker pen. Ensure you are satisfied with the positioning of the accessory. The remaining holes must go in hand with the accessory.

Step 6. Drill the rest of the holes. Always maintain a steady hand and firmly hold the drill on the kayak plastic. Do not sweep away the drill shavings as they will help you seal the drilled holes.

Step 7. Time to attach the accessory to the kayak. Dip the screws in a waterproof silicone sealant and use a screwdriver to lock up the screws. The silicon sealant will fill the space as the threads turn into the hole. Remember to smear some of the silicon sealants on the head of the screw to reinforce the seal.
