Screw or bolt to deck?

[flatscat1]

I'm attaching a cooler tie down to my deck. It comes with stainless screws, as the pictue shows. However, I could easily bolt it to the deck too (I have easy access to the underside through storage hatches.)

Shoul I screw or bolt? Do I need any 5200 or Marine Tex to lock the screws in, if I don't use bolts? If I do bolt it, do I want metal washer or plastic washer on the underside before the lock nut?

Thanks,

If you can, it's always better to thru-bolt. Don't forget to chamfer, or countersink, your holes to prevent gel coat spidercracks.

Very good advice. Do you tape the area before drilling or does it matter?

Really isn't necessary with a good bit. I actually prefer to use a separate counter-sink bit over the bit/countersink combos.

Thu bolt & 5200.

Clean up w/ paint thinner.

I would coat the inside of the holes good with some 5 minute epoxy if you go through any wood. Its always good to seal any exposed core in case the caulk ever fails.

Bolt

Suggest thru bolt with lock nuts and backing plates.
