Stainless steel slate hooks are the go-to fixing for attaching natural or fibre cement slates to timber battens, and these A4-316 marine grade hooks are about as good as it gets for long-term performance on UK roofs. Whether you’re re-slating a full pitch or swapping out a handful of cracked slates on a Victorian terrace, these give you a clean, reliable fix without the fuss of drilling and nailing from below.
Each hook either drives into the batten via a spike end or wraps around it using an S-hook profile, depending on the variant you select. The spike end suits new work where you have clear access to the batten face. The S-hook and batten end types are better for working on existing roofs where getting a nail in cleanly just isn’t practical. It’s the kind of flexibility that matters when you’re two storeys up on a cold Tuesday.
Choosing the Right Stainless Steel Slate Hook Size
Hook length is determined by the head lap of your slates, not the slate length itself. The rule is straightforward: hook length equals head lap plus 2 to 3mm. So for a 120mm head lap, you want a 122 to 123mm hook. Get this wrong and you’re either leaving the hook proud or not engaging the batten properly. The table from the existing spec data is worth following: a 200mm pitch with moderate exposure calls for a 140mm lap, meaning a 142 to 143mm hook. Plan before you order.
These hooks are available in wire diameters of 2.70mm and 3.00mm, with the heavier gauge suited to larger slates or where loading is a consideration. Colour options include black, dark grey, light grey and green, so they can be matched to the slate finish and kept visually tidy under the overlap.
The A4-316 grade is the specification to use in coastal locations, industrial areas or anywhere with persistent salt exposure. The colour coating is decorative and typically lasts ten years or more, though it won’t hold up indefinitely in abrasive salted-wind conditions. Corrosion resistance comes from the steel grade itself, not the coating.
Pro Tip: When ordering for a full roof, calculate your hook length from the head lap first, then factor in pitch and local exposure conditions using the standard lap table before you place the order — getting this wrong on a 500-box buy is an expensive mistake.
Slate hooks are used across new-build and re-roofing work wherever natural slate or fibre cement slates are fixed to timber battens. They are particularly common on repairs and individual slate replacements where traditional nailing from below is awkward or the original fixing method has failed. Roofers working on period properties, conservation projects and coastal buildings often specify A4-316 stainless hooks specifically because the grade holds up in environments where lesser fixings will corrode within a few years.
These hooks see regular use on residential roofs, agricultural buildings and any project where long service life is a priority over the lowest possible unit cost. The colour-coded options make them useful on visually sensitive work where exposed fixings need to blend with the slate profile.

Key Properties
A4-316 marine grade stainless steel
Suitable for coastal and industrial environments
Colour coating lasts 10+ years in normal conditions
Hook length = head lap + 2 to 3mm
Alternative to copper clout nails
Corrosion resistance from steel grade, not coating
Not suitable for: Not suitable for fixing plain tiles, clay pantiles or any roof covering that requires a nail-through fixing. The colour coating will degrade faster in heavily abrasive conditions such as direct salted wind exposure, though the underlying A4-316 steel will remain sound.
Select the hook size by adding 2 to 3mm to your calculated head lap. For spike-end hooks, position the hook so the spike is driven firmly into the face of the batten, with the lower hook tail engaging the underside of the slate. For S-hooks and batten-end types, hook the upper end over or around the batten before positioning the slate.
Ensure the hook sits flush against the batten and that the lower tail is correctly seated in the tail end of the slate. A hook that is sitting proud or at an angle will cause the slate to rock and may allow wind lift over time. On repairs, take care to remove any remnants of the original fixing before hooking the replacement slate.
Determine the head lap required for your roof pitch and exposure level using the standard lap table
Select the hook length by adding 2 to 3mm to the required head lap measurement
Choose the appropriate hook type: spike end for new battens, S-hook or batten end for existing roofs
Select wire gauge based on slate size and loading, with 3.00mm for larger or heavier slates
Position the upper end of the hook against or over the batten, aligning it with the slate centre
Drive spike-end hooks firmly into the batten face using a hammer, ensuring the hook sits square
Lower the slate into position so the tail rests correctly in the hook
Check that the slate lies flat with no rocking before moving to the next course
How do I work out which hook length I need?
Hook length equals head lap plus 2 to 3mm. The head lap itself depends on your roof pitch and local exposure conditions. As a general guide: a 200mm pitch roof in moderate exposure requires a 140mm head lap, so you'd want a 142 to 143mm hook. Use the standard lap table for your specific pitch and exposure, then round up to the nearest available size.
Is A4-316 stainless steel necessary, or will a lower grade do?
For coastal locations, seafront properties and industrial areas with airborne pollutants, A4-316 is the only grade that can be reliably guaranteed against corrosion over the long term. In sheltered inland locations a lower grade may be acceptable, but for anything exposed to persistent salt or chemical atmosphere, 316 is the correct specification and worth the extra cost given it's going under the slates for decades.
Manufactured from A4-316 austenitic stainless steel wire, these hooks offer strong resistance to chloride-induced corrosion, making them suitable for marine and industrial environments where standard stainless grades would eventually fail. The colour coating is applied post-forming and is purely aesthetic; it carries no corrosion protection function. Wire diameters of 2.70mm and 3.00mm cover the typical range of slate weights and batten conditions encountered in UK roofing work.
