WALCUR Spengler Screws ø 4.5 x 25 mm Stainless Steel Self Drilling Decking 100 Pcs Leak Proof Roofing with Rubber Washers

DURABLE & RELIABLE PERFORMANCE - Our spengler screws are made with A2 stainless steel (18% chromium and 8% nickel). This plumper screw set resists corrosion and rust and provides high hardness, strong resistance, and a smooth, burr-free finish. LEAK-PROOF PROTECTION - Each torex screw has a pre-mounted plate washer with an EPDM sealing washer. This creates a watertight seal to prevent leaks, dirt, moisture and protect your structure from water damage. PROFESSIONAL FINISH - The smaller oval countersunk head design on terrace screws provides an unnoticeable end, so your project looks polished without unsightly screw heads. These stainless steel decking screws are also compatible with TX20 screwdrivers for easy installation. CONVENIENT DRIVING - Woodworking screws have a 4 cut nip that allows faster and more precise driving, reduces splitting and the screwing torque. With a self-tapping wood thread feature, you may avoid pre-drilling. Due to the lubricating coating and partial thread pitch, screwing self-tapping screws is fast with little effort.
