12 x 50mm Type 17 Hex Timber Screws 100 Pack
The 12 x 50mm Type 17 hex timber screw is a structural timber fastener with a neo sealing washer and a Class 4 coating. The Type 17 point cuts its own path into timber without pre-drilling, the hex head drives with a nutsetter, and the EPDM sealing washer keeps the fixing point watertight and UV resistant. At 50mm it is the everyday length for cladding, roofing and fencing fixings into timber, supplied in a 100 pack.

Frequently Asked Questions
Why choose the 50mm length?
At 50mm the screw reaches through cladding or a sheet and grips firmly in the timber batten or purlin below, which is why it is the everyday length for roofing and cladding fixing.
Do I need to pre-drill?
No. The Type 17 point cuts its own path into timber as the screw drives, so there is no pilot hole needed in most softwoods and hardwoods.
What does the neo washer do?
The EPDM sealing washer compresses under the hex head to seal the fixing point against water and UV, keeping the fixing weathertight in exposed positions.
Is Class 4 coating suited to outdoor use?
Yes. Class 4 is a corrosion-resistant coating for exposed outdoor work, giving the screw a long service life in Australian conditions.
