Description

AM Steel Pin Type Anchors are one-piece, hammer-set expansion anchors comprising an expansion body and a pre-assembled centre pin (nail), designed for fast, single-action fixing into solid concrete, brick, and masonry. Manufactured under the AM Steel brand, these anchors (widely known as hammer drive anchors, nail-in anchors, or hammer-through anchors) work by driving the centre pin down into the body with a hammer – expanding the anchor walls outward against the wall of the pre-drilled hole to lock it firmly in place in a single step.

Because the anchor is placed straight through the fixture and into the hole and set with a couple of hammer blows, AM Steel pin type anchors are a fast, economical through-fixing for high-volume, light-to-medium-duty work. They’re the go-to choice for fixing timber battens, door and window frames, skirting and trim, wall brackets, conduit and cable clips, and metal profiles to solid walls, floors, and ceilings – anywhere many fixings must go in quickly. Available with a countersunk head for a flush finish or a mushroom/round head for surface fixing over the fixture, the pin head sits neatly once driven, and some versions allow removal by unscrewing the pin. AM Steel pin type anchors are available in zinc-plated carbon steel for general indoor construction, and in stainless steel (A2/304 and A4/316, the latter considered marine-grade) for outdoor, wet, or corrosion-prone environments.

Whether you’re fixing battens and frames, mounting brackets and trim, securing conduit and cable runs, or handling any high-volume light fixing into solid masonry, AM Steel pin type anchors deliver the fast hammer-set installation, reliable expansion grip, and consistent quality needed for economical through-fixing. As with all AM Steel products, this pin type anchor is available in a range of metric sizes (typically 5mm to 10mm diameter, lengths from around 30mm to 160mm), in countersunk and mushroom head styles, and in multiple materials and finishes to suit both industrial-grade and everyday fastening needs.

Ideal For

AM Steel Pin Type Anchors are ideal for:

• Carpenters and fit-out trades fixing timber battens, door and window frames, skirting, and trim to solid walls
• Electricians and services installers securing conduit, cable clips, trunking, and mounting brackets at high volume
• Bracket, profile, and fixture mounting where fast through-fixing into masonry is needed
• Builders needing an economical, quick-set anchor for repetitive light-to-medium-duty fixings
• General construction and maintenance requiring a single-action hammer-in anchor into concrete or brick

Choosing the Right Pin Type Anchor

Selecting the correct pin type anchor from the AM Steel range depends on several factors:

• Material – Stainless steel (A2/304 or A4/316) for outdoor, wet, or corrosion-prone applications; zinc-plated carbon steel for general indoor and dry construction.
• Head Style – Countersunk head for a flush finish where nothing should protrude; mushroom/round head for surface fixing that clamps over the fixture.
• Base Material – Confirm the anchor suits the base — solid concrete, brick, or masonry; expansion anchors need solid material, not hollow or lightweight block.
• Diameter & Length – Choose a diameter to match the drilled hole and a length that passes through the fixture and provides adequate embedment into the base for the load.
• Load Level – Pin type anchors suit light-to-medium-duty loads; for heavier structural fixings, a bolt-tightened or setting-tool expansion anchor may be more appropriate.
• Removability – If the fixing may need removal, choose a version whose pin can be unscrewed rather than a permanent hammer-set type.

Strategies to Choose the Right Product

• Match the anchor to a solid base material – Pin type expansion anchors need solid concrete, brick, or masonry to expand against; they are not suited to hollow or lightweight materials.
• Drill the correct hole size and depth – Use the specified drill diameter and clean the hole of dust so the body expands fully and grips reliably as the pin is driven.
• Choose the head for the finish – Countersunk for a flush, snag-free result; mushroom/round where the head should sit over and clamp the fixture.
• Match material to environment – Use stainless steel (A2/304 or A4/316) for outdoor, wet, or coastal work; zinc-plated carbon steel for general dry, indoor construction.
• Keep to light-to-medium-duty loads – For high or safety-critical structural loads, step up to a bolt-based or setting-tool expansion anchor with rated holding values.
• Consider bulk vs. individual packs – Bulk packs suit batten runs, conduit, and repeat construction fixings; smaller packs suit repairs or single installations.

Frequently Asked Questions (FAQs)

1. What is a pin type anchor used for?
A pin type anchor is used for fast through-fixing of battens, frames, brackets, conduit, and cable clips into solid concrete, brick, or masonry, setting in a single hammer action as the centre pin is driven into the anchor body.

2. How does a pin type anchor work?
The anchor is placed through the fixture into a pre-drilled hole, then the integral centre pin is driven in with a hammer, forcing the body to expand outward against the hole wall and locking the anchor firmly in place.

3. What’s another name for a pin type anchor?
Pin type anchors are also known as hammer drive anchors, nail-in anchors, hammer-through anchors, or drive pin anchors, all describing the same hammer-set expansion fixing.

4. Are AM Steel pin type anchors different from generic hammer drive anchors?
AM Steel pin type anchors are manufactured and quality-tested under the AM Steel brand, ensuring consistent expansion performance, pin fit, head dimensions, and finish across every batch.

5. What base materials can pin type anchors be used in?
Pin type anchors are designed for solid base materials – solid concrete, brick, and masonry; they are not suitable for hollow or lightweight block, where the body cannot expand against a solid wall.

6. Do I need a bolt or setting tool for a pin type anchor?
No – unlike bolt-tightened or setting-tool anchors, a pin type anchor is a one-piece fixing set with just a hammer, making it faster and more economical for high-volume light-duty work.

7. What sizes do pin type anchors come in?
AM Steel pin type anchors are available in a range of sizes, typically 5mm to 10mm in diameter, with lengths from around 30mm to 160mm, in countersunk and mushroom head styles.

8. What’s the difference between a countersunk and mushroom head pin anchor?
A countersunk head sits flush with the surface for a clean, snag-free finish, while a mushroom or round head sits proud and clamps over the fixture, spreading load across a wider bearing area.

9. Are pin type anchors corrosion-resistant?
Yes, especially AM Steel stainless steel versions (A2/304 or A4/316), which resist rust in outdoor, wet, or coastal environments; zinc-plated carbon steel suits general indoor and dry conditions.

10. How much load can a pin type anchor hold?
Pin type anchors are intended for light-to-medium-duty loads; for high or safety-critical structural fixings, a bolt-based or setting-tool expansion anchor with rated holding values is more appropriate.

11. Can pin type anchors be removed or reused?
Many are a permanent fixing once the pin is driven, though some versions allow the pin to be unscrewed for removal; the anchor body is generally not designed to be relocated once expanded.

12. Do I need to pre-drill a hole for a pin type anchor?
Yes – a correctly sized hole must be drilled to the specified diameter and depth, then cleaned of dust so the body can expand fully and grip when the pin is driven.

13. What’s the difference between A2 and A4 stainless steel pin type anchors?
A2 (304) stainless offers good general corrosion resistance for most outdoor use, while A4 (316), considered marine-grade, provides superior resistance to chlorides and coastal or chemical environments.
