10 x 5/8 SPAX Wood Screws, Clear Zinc Plated Steel, Pan Head, Combo Drive - QTY:1000 - 3GYE5

SPAX combines a fully-threaded shank (for most versions) with a patented serration pattern, a patented head style called the MULTIhead, which countersinks the head flush with most materials, and a patented point called the 4CUT ™ which eliminates pre-drilling and splitting because of its square end which divides wood fibers.

That combination of the 4CUT ™ point and serrated thread is effective enough to eliminate pre-drilling unless you're driving into either masonry or sheet metal better than 24 gauge. SPAX ® have the German building code approval.
