## Description

Product Description FastenMaster LedgerLOK is the first wood screw engineered to fasten a deck ledger board to the rim joist of a house with no predrilling. The built-in washer head eliminates the need for an additional washer, saving time and money. The large hex-head allows for greater bit engagement, reducing cam-out.LedgerLOK replaces traditional 1/2 inch lag bolts, installing in a fraction of the time, and leaving you with a code-compliant, secure ledger to rim board connection. LedgerLOK is guaranteed to last for the life of the project.Refer to the LedgerLOK technical bulletin (included in each box) to determine the fastening pattern for your specific application.Includes 250, 5 inch ledger board screws, and 1 hex driver bit.Since 2003, thousands of PROs have trusted LedgerLOK to make ledger to rim board connections - its reliability and easy of use make it a staple on jobsites everywhere. From the Manufacturer Save time, money, and labor costs. LedgerLOK is the first fastener engineered to attach deck ledger boards to the rim board of the house with no predrilling. No need to predrill and hand-ratchet in 1/2 inch galvanized lags and washers. LedgerLOK also has stronger shear values than 1/2 inch galvanized lag screws. Plus, with LedgerLOK's smaller shank diameter, even a cordless drill (14.4 volts or higher) zips them right in, saving on battery life and additional tooling costs. Each pack size contains a free 5/16 inch driver bit. LedgerLOK fasteners are American made.

Review: Can't Beat It !!! - I have searched my local area stores for the best price and the price on these far exceed the prices I have found anywhere. The fastener itself is the best out there... I bought these for a project at home. I have used these many times for decks and other building projects. This time seemed to make me really appreciate how awesome they really are... I used these to build a 4 tiered garden in the back yard with landscape timbers. Our yard slopes drastically and I wanted to dress it up and be functional about it. I built the retaining walls with landscape timbers and screwed each course of timbers together with these. The ledgerLOKs are so powerful that I was able to drive bows out of the not so perfect timbers. As I fastened them, I would countersink them so as to not have them sticking up in the way of the next course. They had so much torque to them as they were countersinking, they would squeeze the water right out of the timbers. It was really cool. I know it's a guy thing but WOW. My wife even confirmed how cool it was after watching a small demonstration. Will Not Be Disappointed and much less in price per unit cost...
Review: Great product and code approved - Notice the name is LedgerLOK and were created to attach ledger boards to your house when building a deck. However, they are a universal type product that can be used for many applications. They are code approved in most geographic locations as replacements for 3/8 inch lag bolts. Pre-drilling is not required. I use Milwaukee M18 impact driver and there is enough power to drive through tough wood. Some low torque impact drivers may have trouble with the screws. I've been using these screws for 3+ years. I'm just a serious home maintainer and woodworker (Not Commercial)
