    These fasteners are amazing. If you’re doing any kind of framing, you’ll know Simpson is the standard. May be more expensive than others, but you get the strength and quality with this brand. They drive easy and hold tough. Only brand I’ll buy.

    I’ve got a La-Z-Boy rocker recliner that I busted the springs on and snapped a few of the screws and decided on whether or not to nut and bolt the replacement springs back on but this was a more feasible option.
    I purchased these back in August of 2022 it is currently March of 2024 I have rocked this chair daily and am still rocking it today and plan on rocking it for years to come hopefully. Or at least till the fabric wears out cause Lord knows the screws will out last that!

    The failed factory screws caused the springs to snap when I replaced with these I have not had any issues so I highly recommend these for any structural needs.
