ST Fastening #12 x 3/4" Kwikseal Woodbinder Metal Roofing Screws - Brown (250 Pack) - Corrosion Resistant Metal to Wood Fasteners for Roofing, Siding & Construction Projects

FEATURES POWERFUL COATING SYSTEM 2.5 mil of computer controlled powder coat is applied over zinc plating and chromate sealerUnique polyester powder formulation resists harmful UV rays and chemical breakdownPOWDERFUL is completely free of volatile organic compounds (VOC), and is entirely recyclable FEATURES AND BENEFITS KS V-NECK HEAD DESIGN HWH with V-neck design adds strength to prevent head twist off under extreme torqueUV resistant EPDM rubber is vulcanized to a G-90 steel backed washer to provide maximum sealing ability, which prevents leaks, even when drilled at an angleHigh tensile steel washer provides excellent pullover strengthST MAGNETIC SOCKETS are designed with an advanced forging process to fit the painted fastener securely, which helps to prevent fastener wobble upon installation KS LO-ROOT THREAD DESIGN Fastener thread transitions from fine to coarse. The low root design provides excellent pullout strength versus traditional or HI-LO thread forms MICRO-BIT POINT DESIGN Drill point design consistently penetrates metal panels, which eliminates the need to “punch” the metal panels with a sharp point to start the drilling processMB point is excellent for penetrating multiple thicknesses of steel often found on ridge cap or trim applications FEATURES AND BENEFITS KS V-NECK HEAD DESIGN HWH with V-neck design adds strength to prevent head twist off under extreme torqueUV resistant EPDM rubber is vulcanized to a G-90 steel backed washer to provide maximum sealing ability, which prevents leaks, even when drilled at an angleHigh tensile steel washer provides excellent pullover strengthST MAGNETIC SOCKETS are designed with an advanced forging process to fit the painted fastener securely, which helps to prevent fastener wobble upon installation KS LO-ROOT THREAD DESIGN Fastener thread transitions from fine to coarse.

ST Fastening Systems sockets are designed to allow for the added thickness of the powder coat. The combination of the Micro-Bit point & transition thread from fine to coarse generates superior drill speed in metal & holding strength in wood substrates.

[COATED SCREWS] 2.5 mils of computer controlled powder coating that will not chalk or fade due to UV inhibitor in all colored coatings.

[KS V-NECK HEAD DESIGN] HWH with V-neck design adds strength to prevent head twist off under extreme torque.

[EPDM RUBBER WASHER] Vulcanized to a G-90 steel backed washer to provide maximum sealing ability, prevents leaks, even when drilled at an angle

[KS LO-ROOT THREAD DESIGN] Fastener thread transitions from fine to coase. The low root design provides excellent pullout strength vs traditional or Hi-Lo thread forms

[MICRO-BIT POINT DESIGN] Design consistently penetrates metal panels, which eliminates the need to "punch" the metal panels with a sharp point to start the drilling process
