Can this replace 5/16in Galvanized Hex Bolt, Nut & Washer for deck mounting rail post?

This question is from ThruLok 24-Piece 8 in. Screw Bolt Fastening System

Read all my Q&A
April 3, 2016
The surface mount post sleeve I am looking to purchase only comes with bolts for concrete surface application. However, the application I am using it for will be of composite decking and pressure treated wood structure. The post sleeve product recommends using 5/16in x 5in galvanized bolts, 5/16in galvanized nuts & 5/16 galvanized fender washers. Unfortunately, my local hardware store does not sell the 5/16in nuts and washers - only the 5/16in carriage bolts. Is your Thrulock screw bolt fastening system a good replacement for this requirement or do you have another product that will do the job better?

Rated 5.0 out of 5.0 by Cant believe how easy they work My sons have used these on a couple of projects and they work well, are fast to install and require no added tools. My 7 and 13 year old sons used these to attach handrail brackets to 6x24 inch beams and they installed 48 of them with a Hole Hog in under 30 minutes. May 14, 2015
Rated 5.0 out of 5.0 by ThruLok SWEET This has got to be the best and easiest way to put lumber together. No holes to drill out before you put a lag-bolt in place... Just level the boards together and screw in the ThruLok and fasten on. A must for working on decks. THANKS February 25, 2014
