Sheradised annular ring shank nails in a 25kg bulk box. Available in sizes from 25mm to 100mm. The ring shank profile locks into timber and resists pull-out far better than a smooth wire nail. Built for outdoor and structural timber work.

Sheradised nails are the go-to fixing for any timber work that needs to stay put. The annular ring shank profile bites into the wood fibres as the nail is driven, creating a mechanical grip along the full shank length. That grip resists pull-out forces that would work a smooth nail loose over time. The sheradising process coats the steel with a bonded zinc layer, giving genuine corrosion resistance without the weight or cost of hot-dipped galvanised product. These are sold in 25kg bulk boxes and are available in sizes from 25mm through to 100mm, covering most structural and cladding applications on site.
Ring shank nails have been the standard for timber decking, fencing, cladding, and flat-roof boarding for decades. The ring profile means the nail resists the seasonal movement that timber goes through as it wets and dries — the kind of movement that slowly backs a smooth nail out of the surface until you are left with a row of popped nail heads across your decking boards. That is a problem ring shank nails simply do not have to the same degree.
Why Sheradised Annular Ring Shank Nails Are Preferred for Exterior Timber
The sheradising treatment is applied by tumbling the nails with zinc dust at high temperature, producing a diffused zinc-alloy coating that bonds into the steel surface. This gives better adhesion and abrasion resistance compared to electroplated zinc coatings, and it means the coating holds up during driving rather than being stripped off by the gun or hammer head. For exterior work where nails will be in contact with treated timber, sheradised nails are a practical and cost-effective choice. Tanalised and pressure-treated timbers can cause rapid corrosion of uncoated or lightly coated nails, so getting the nail specification right matters.
Buying in a 25kg box is the sensible option for any contractor who is running through volume on a decking project, a fencing run, or timber frame work. You are not paying a premium per kilo for small pack convenience, and you have enough on site to get the job done without a mid-job trip to the merchant. The range of sizes in this listing means you can spec the right nail for the board thickness rather than making do with whatever is available.
Pro Tip: When nailing into pressure-treated or tanalised timber, always use sheradised or hot-dipped galvanised nails rather than bright steel, as the preservative chemicals in treated wood will corrode uncoated nails within months and stain the timber surface.
Annular ring shank sheradised nails are used across a wide range of exterior and structural timber applications. Decking boards, fence panels, feather-edge cladding, soffit boarding, and flat-roof deck sheets are the most common uses on residential sites. Housebuilders and groundworkers also use them for temporary shuttering and hoarding where pull-out resistance matters. Roofing contractors reach for ring shank nails when fixing sarking boards and timber purlins, where a nail being worked loose by wind uplift or thermal movement is not acceptable. The 100mm size handles structural work in thicker section timber, while the smaller sizes suit cladding, fascias, and secondary boarding.

Not suitable for: Not suitable for use with stainless steel fixings requirements where marine-grade corrosion resistance is specified. Not recommended for masonry, concrete, or metal fixing applications.
Select the correct nail length for the material being fixed. A general rule is to use a nail at least two and a half times the thickness of the board being fixed, so a 25mm cladding board would typically take a 65mm nail to give adequate penetration into the substrate. Drive the nail straight and true to avoid splitting the board, particularly near the ends of timber where splitting is most likely. Pre-drilling near board ends is worth the extra minute if the timber is dry or has a tendency to split.
For flat-roof deck boarding, the ring shank profile is especially important as the boards are subject to movement and wind uplift. Ensure nails are driven flush but not punched through the surface, which can compromise the weatherproofing layer applied over the top.
Select the correct nail size for the board thickness, aiming for penetration of at least two and a half times the board depth into the supporting timber
Check that the timber substrate is sound and that the fixing point is over a joist, rafter, or solid bearer rather than a gap
Pre-drill near board ends in dry or resinous timber to prevent splitting
Drive the nail in a single controlled pass where possible, keeping the angle straight to maximise the ring shank grip
Drive the nail flush with the surface rather than punching it below on decking or cladding, unless specifically required by the system being installed
Inspect nails for any damaged or bent shanks before use and discard any that show damage to the ring profile
What is the difference between sheradised nails and galvanised nails?
Both sheradised and galvanised nails have zinc coatings, but the process differs. Sheradising bonds zinc dust into the steel surface at high temperature, producing a hard, abrasion-resistant coating that holds up well during driving. Hot-dipped galvanising produces a thicker zinc layer and is generally considered the higher specification for very aggressive environments, such as coastal sites or direct ground contact. For most exterior timber work including decking, cladding, and fencing, sheradised nails are the practical and cost-effective choice.
Can these ring shank nails be used in a nail gun?
Annular ring shank nails in loose bulk form are designed for hand nailing or conventional hammer use. Nail guns typically require nails to be collated into strips or coils in a specific configuration matched to the tool. If you need ring shank nails for a pneumatic or gas nail gun, check the collation format and nail gauge required by your specific tool before ordering loose bulk nails.
Annular ring shank sheradised nails are manufactured from steel wire with a series of rings rolled along the shank, increasing the surface area in contact with the timber and generating significant resistance to withdrawal forces. The sheradising process applies a zinc-alloy diffusion coating, typically achieving coating thickness comparable to Class 2 protection requirements for exterior timber applications. The ring profile is produced during wire forming prior to coating, ensuring the zinc layer is applied uniformly over the finished shank geometry.
