#8 x 1-1/4 in. Philips Bugle-Head Coarse Thread Sharp Point Polymer Coated Exterior Screw (1 lb./Pack)

A:  I would check with the manufacturer but I can't imagine why not.

A:  We used these screws when building a greenhouse. I wish we had used glue along with the screws on the wavy boards that the siding is screwed into. Over the last year, we have noticed that the boards have warped a little and have pulled apart and the screws alone didn’t hold. 

A:  We cannot recommend uses for this nail outside of published application and uses.

A:  Stainless screws are better

A:  These are designed for exterior wood to wood applications and we cannot recommend use in applications that these are not designed for.

A:  Yes they will work for exterior. Be sure to pre drill and countersink screw holes before installing screws. Otherwise you may crack or break the pvc trim.

A:  Approximately 150

A:  Approximately 205 per pound

A:  I can't advise you on this question as I used them in repairing a broken lazy back chair kept indoor. I would not hesitate to use in wet conditions, but are they better than stainless ? Price & hardness I think is better, but in the long run stainless will out live them but cost more up front.

A:  Yes, that application is one of the reasons coated screws are made.

A:  Yes it is good for PT lumber.
