Which Type 17 screw?
- Bugle batten screw (ribbed head, internal hex drive): fixing roofing battens to timber rafters and trusses, and heavy timbers. Also in 304 and 316 stainless.
- Flanged hex and hex with seal (Class 4, Scratchguard): fixing steel roofing and cladding to timber battens and frames.
- Self-embedding head (304 stainless, square drive): timber decking in corrosive environments and treated pine. The ribbed head embeds flush with the board.
- Countersunk Torx: treated pine and outdoor furniture, with a T25 Torx drive for a positive fit. No pre-drilling needed.
- Pan, wafer, button and trim heads: general timber fixing and trim.
Type 17 sizes and embedment
Type 17 screws are sized as gauge and threads per inch: a 14-10 is a 14 gauge screw (6.3mm thread) with 10 threads per inch, the usual batten and heavy timber screw; 12-11 (5.5mm) suits lighter work; 10-12 (4.8mm) and smaller suit decking and trim.
For full pull out strength in timber, embed at least 25mm for a 12 gauge screw and 35mm for a 14 gauge screw. Choose a length that gives that embedment after passing through the batten, sheet or board.
Class 3, Class 4 or stainless?
Class 3 suits sheltered and moderate sites, and Class 4 the more corrosive ones. Use 304 stainless for decking and wet areas, and 316 stainless near the coast. For treated pine, Hobson lists its 304 stainless self-embed head screw for timber decking in corrosive environments and as suitable for treated pine, and its Tykote countersunk Torx screws carry a coating specially formulated for resisting treated pine chemicals. Hobson's 316 recommendation for treated timber is in its coach screw guide and applies to coach screws.
Driving Type 17 screws
- Use the right bit: hex socket, internal hex, Torx or square to suit the head.
- Hold the screw square and apply firm, steady pressure while the point cuts in.
- Drive until the head seats. Self-embedding and bugle heads should finish flush; do not overdrive.
