What row are these in the store

Asked by Spike January 8, 2020

Answer

Typically a special-order item in my city. If they are stocked locally, the webpage for the item will give the aisle number, bay number, and quantity on hand.

what diameter is it as well the hex sixe

Asked by steve November 1, 2019

Answer

The screw is 0.276"-diameter and it has a 3/8" hex drive. Thank you!

What are these screws made of to justify a quantity of 30 for $126? Space shuttle steel?

Asked by Mike March 5, 2019
1
Answer

I wondered the same. Really defeats the purpose of "UPCYCLED" or "LOW COST" when building raised bed garden. I did find a more affordable alternative: OZCO brand 1/4"×12" self-tapping OWT (Ornamental Wood Ties) 10pk = $25.23 They don't seem to be regular stock but they can be ordered for delivery to the store.

Can this be used with ground-contact grade pressure treated wood?

Asked by sadfasdfw March 4, 2018
1
Answer

Type 316/305/304 stainless steel products are recommended where preservative treated wood used in ground contact has a chemical retention level greater than those for AWPA UC4A. Thank you!

I'm building a deck and the code calls for a 1/2 in bolt to be used to attach a 4x4 post to a double 2x6 beam. What product of yours can I use?

Asked by Roman June 14, 2016
1
Answer

I'm not clear on the application, but please see page 13 of the F-DECKCODE13 (on our website) for Beam-to-Post Connections for various applications. Thank you!
