Series 500 Hex Head Tek Screws

Series 500 Tek Screws

Heavy duty series 500 screws from our tek screw metal self drilling screw range. Features include hex large diameter washer head offering a large surface area for a strong clamping action and a hardened shank with extra long drill points for fastening directly into thick steel.

Our Series 500's are fine thread screws designed for maximum clamping force into thick steel sections. These self drilling screws will self drill directly into steel thickness's up to 8mm and negate the need for pre drilling in sections where traditionally a pilot hole would have had to be drilled. The series 500 self drilling screws will screw into all steels, including hot rolled steel, I beams, thick steel purlins or any thick steels up to their maximum capacity. For improved drilling capacity up to 12mm check out our series 600 screw range.

Series 500 Screws are designed for high strength fastening of brackets, components, steel sections, assemblies and sheeting to heavy gauge steel up to 9mm thick, 24TPI fine thread with a 20mm drill point length. 5/16" hex head and high performance class 4 galvanised for premium corrosion protection.

Series 600 Hex Head Tek Screws

Series 600 Tek Screws Self Drilling Hex Head

Our Super High Performance series 600 hex head tek screws drill faster, easier and deeper than any other metal self drilling screws on the market. Their amazing performance comes from the 8 hardened cutting faces which are individually machined into each screw (as opposed to continual feed and forged manufacturing) which makes these screws operate more like individual drill bits.

Designed for maximum performance in the toughest of steels and they drill deeper than any competitor product, at an incredible 15mm drill capacity. These are a premium engineered ceramic coated metal self drilling tek screw for customers requiring consistent high performance.

8 blade hardened and machined drill bit cutting faces.
Can be used in steels from 1mm up to 15mm thick.

Wing Tip Tek Screws

Scrooz Wing Tip screws are professional grade high performance self drilling fasteners for fixing timber to metal in a single operation without the need for pre-drilling. Manufactured with a ribbed countersunk self embedding head giving a flush finish in the timber.

Ideal for fixing timber boards, battens and general timber to steel sections. Due to the different rates of expansions of the timber and steel there is a possibility of screw shearing. This is solely down to timber movement.

Although this is a very rare occurence (less than 0.5% of cases), due to the volume of wing tip screws we sell for decking boards, all customers must be aware we accept no liability for any screws shearing due to differential timber movement as this is not something under our control.

Methods to reduce timber movement would be sealing, proper ventilation, correct spacing and suitable drainage eliminating standing water. Contact us for more advice regarding your specific application if you are unsure.

For fixing 19mm or 22mm decking boards you'll need a 10g x 45mm length screw.

Self drilling hardened points for fast insertion and self centred start.
No2 square drive for a positive connection avoiding 'tear out'.
Hex 5 drive for 14g wing tip metal self drilling screws.
Countersunk head type fpor a flush finish.
Parallel thread providing a constant and even clamping load.
Heavy duty high strength shanks designed for use with high torque cordless screw drivers.
Thread cutting profile with a coarse tapping thread for rapid installation.
