These Forgefix Phillips, single thread Drywall Screws have a black phosphate finish for increased durability. The screws come complete with a Phillips No.2 insert bit. Their Bugle Head allows the screw to sink effortlessly into the dry lining without the need for countersinking, which in turn minimises the damage to the surface. APPLICATION:Designed for fitting dry linings to studding. Phosphate coatings are made up of thin crystalline layers of phosphate compounds that adhere to the surface of the fixing or fastener. The phosphate crystals are porous and can be formed from zinc, manganese, or iron phosphate solutions. Phosphate coatings offer good corrosion resistance and have an excellent ability to absorb supplementary coatings which improves appearance, corrosion resistance and resistance to abrasion. The Phillips screw has four simple tapered slots. It is designed so that a Phillips tip screwdriver can turn a Phillips screw with increasing torque. When the torque gets to be too strong for the tip then the screwdriver tip winds itself out of the screw thus preventing over-tightening and or damage to the screw head. Coarse thread screws (mainly drywall screws) have an extremely sharp point and are designed to penetrate plasterboard skin. The coarse thread eases in to the board then the timber baton holding the board firm.Drywall Screw Phillips Bugle Head SCT Black Phosphate 3.5 x 38mm Bulk 1000
Forgefix TechFast Timber to Steel CSK/Wing Screws are used to join timber to steel frame buildings. The screws are fitted with breakaway wings that create a clearance hole to protect thread from engaging timber when drilling through. Breakaway wings will ream a hole, then break-off when they contact the metal surface to be drilled. The thread will then engage with metal. They have a TORX® compatible insert for a higher transmission of power. With improved countersinking from recessed ribs. Fire and corrosion resistant. Complies with EU Safety, Health and Environmental requirements.These Forgefix TechFast Timber to Steel CSK/Wing Screws have the following specification: Size: 5.5 x 60mmClamping Thickness: 40mmEffective Thread Length: 39mmPack Size: 100Drill Tip: No.3 No.3 drill tip for self-drilling heavy gauge steel up to 5mm.
Forgefix TechFast Composite Panels to Steel Hex Screws are used to join composite panels to steel frame buildings. They have a specially designed compression control thread to prevent damage and denting of panels. They are fire and corrosion resistant, protected by Elementech corrosion resistant coating, salt spray tested to 1000 hours. Complies with EU Safety, Health and Environmental requirements. They are supplied with 16mm EPDM rubber washers.These Forgefix TechFast Composite Panels to Steel Hex Screws have the following specification: Size: 5.5 x 80mmInsulation Thickness: 63-129mmPack Size: 100Drill Tip: No.3 No.3 drill tip for self-drilling in heavy gauge steel up to 5mm.
These Forgefix General Purpose Pozidrive Screws with Countersunk heads are zinc plated for increased durability. They are an extremely popular general purpose screw, and suitable for use in and with many materials. APPLICATION:Ideal for use in many ironmongery, electrical and plumbing applications.Can be used with various screw cover caps. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrate’s surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers. The Pozidriv screw is similar in appearance to the classic Phillips cross-head, but in fact is very different. The Pozidriv has four additional points of contact, and does not have the rounded corners that the Phillips screw drive has. The biggest advantage it offers is that, when used with the correct tooling in good condition, it does not cam out, allowing great torque to be applied. The Pozidriv screw can easily be distinguished by a line embossed in the screw head at 45° to the slots for the driver. The countersunk head is designed to sink flush with substrates to leave a smooth surface finish. They have twin threads, which enable an easy start when driving.
