SPAX PowerLags - Wood Lag Screws

Built-on Washer Head

The low-profile, large diameter head design provides outstanding clamping force and improved aesthetics. Deep T-Star drive offers excellent bit engagement without requiring a “special” driver bit.

Patented Thread Serrations

Patented thread serrations require up to 40% less driving torque to increase installation speed while helping prevent cracking in logs.

HCR Coating

These T-star Washer Head screws are made of carbon steel and feature High Corrosive resistant (HCR) coating which makes these screws ideal for use in treated lumber and exterior applications.

Project-friendly Packages

SPAX PowerLags are sold in project-friendly packaging quantities that help minimize your building material costs: by the piece, 25 or 50 count Contractor Packs, and Bulk Pails (by special order).

I use a lot of these screws or powerlags as SPAX markets them as. I have them in all kinds of thickness and lengths.
But these ones that came is today, (1/4" x 3") were not up to the standard.
The screws are OK, so machining has gone fine, but the HCR coating [HCR® high corrosion-resistant coating option for use in interior or exterior applications, including treated lumber.] is horrible. somebody at the wheel must have fallen asleep and these have passed the final QA and went to distribution. I ordered two packs and they are both the same!

I used these in an outdoor wood planter that I made. I was initially worried as the green coating seems to come off rather easily. But after 6x months (I bought my first box of these fasteners in a local supply store over 6x months ago) in the pressure treated wood plus daily watering of the plants (and surrounding which included/hit the wood and these fasteners), there is still no sign of external rust.

I would highly recommend these, infact I''m writing this review due to my re-order on Amazon.

I used these lags to build H Braces for a fence with 4x4s. I drove them with a battery operated driver using the bit included with these lags. The heads on these are significantly better the heads on the 1/4" x 6" Spaxx which stripped out WAY to easily and quickly. I did have one strip, but was able to back it out before it was completely destroyed. Even that recovery was way better than the 1/4". Other than that, these things drive in tight and really feel sturdy.

I wish the head washer diameter had been stated in the sales info. I was going to use as a lower profile fastener than similar diameter hex head lags to attach U-shaped Rollup Door Guide Rails to framed opening. Unfortunately, the guiderail access holes to drive the screws are only 5/8" wide - D''oh!

But, will definitely use on a ledger install project.

A durable, quality screw ideal for mounting flat surfaces flush without countersinking. Perfect for mounting my hose reel to the side of my house. Surprisingly difficult to find washer head screws at the hardware store.
