Fastenmaster TimberLok Structural Screws, 4 In, Countersunk Hex Washer, Black, Steel, 50/Box

Drives clean, holds tight, and saves you a step.

A steadier build with less fuss.

Product Overview:

On a job site, time has a way of slipping through your fingers. These structural screws help you keep it. Fastenmaster TimberLok screws are made to bite into pressure treated beams without pre-drilling, so you spend less time setting up and more time getting the frame square. The countersunk hex washer head pulls in neatly, and the steel build with epoxy coating gives the screw a tough, practical finish. If you are working on decks, beams, or heavy framing, this box of 50 gives you a steady supply and a cleaner drive. Picture the fastener seated flush, the drill easing off, and the work moving along without a lot of drama.

Key Features:

• No pre drilling needed so you can keep the pace up and move from cut to set without the usual backtracking.
• Countersunk hex washer head helps the screw seat cleanly, leaving a tidy finish that looks right when you notice the details.
• Heat treated steel gives you a harder working fastener that stands up to the kind of force framing jobs throw at it.
• Heavy duty threads grab well in pressure treated beams, so the hold feels solid instead of loose or fussy.
• Easily removable when you need to adjust a piece later, which is a real relief when a plan changes halfway through.
