Customer Reviews for GRK Fasteners #10 x 3-1/8 in. Star Drive Torx Bugle Head R4 Multi-Purpose Wood Screw (70-Pack)

Exactly what I needed for the job

Removable & quieter replacement for 16d galvanized nails, also easier to place accurately when your screw gun fits a tight space better than a restricted hammer swing limitation

Worked out great for our project

These GRK 10 x 3-1/8" R4 Multi Purpose Screws are an excellent fastener. 500+ & zero snapped! The "W Cut" thread makes them drive rather easily. Therefore, no wax is needed & usually no pre-drilling. The heads are cut so precisely that the driver can be at quite an angle and still engage the fastener securely. (The fast start tip helps, too.) These R4 screws actually have a Structural Rating, as found on the GRK web site. Also published are Shear & Torsion ratings, making inspections easier.

Use these for assembling the legs for the loft beds I am building for my granddaughters.

I love the GRK screws! They bite faster and cut through the wood, even through the countersink, much cleaner than the other brand that dominates the screw isle at Home Depot.

Worked great, very good quality!

This type of screw really bites

Completely sold on the quality of GRK multi- purpose star drive screws. They start easily without needing a pilot hole. The hardened steel plus the torx drive prevents them from cramming and striping. They cost more but the quality is so worth it.

Great quality product.

High quality screw. However, the box is not sealed so I decided to count the screws. Quantity 110 on the box. I counted 106, hmmm.

Used to build an above ground grow box. Very solid

Finishing my basement and I've been using these screws for all of my framing. They're awesome! Highly recommend.
