Slide bolt

Start by matching the application with the fastener type and size. For masonry work, choose an expansion bolt such as M10x90mm to secure brackets or rails in concrete or dense stone, noting the total length of 90mm and wedge diameter of 10mm. The bolt is made from Q235 carbon steel with a zinc plated finish that resists oxidation and corrosion. If you’re mounting around pipes or creating clamping points, consider stainless steel U-bolts or saddle fasteners rated for outdoor use. This range includes both to cover common home and workshop tasks.

Expansion bolts anchor into masonry by expanding a wedge inside the drilled hole, providing a strong hold in concrete or stone. The example in this assortment is the M10x90 expansion bolt with a 10mm wedge and 90mm length, paired with zinc plating for durability. U-bolts, such as the 304 stainless steel saddle fasteners, clamp around pipes or rails, offering versatile mounting without drilling through the fixture. Through bolts, like the M12 through bolts sold in packs, pass completely through the fixture and are secured with a nut, ideal for heavy-duty joints.

DIY tasks like mounting brackets, sliding hardware, or wall rails commonly rely on expansion bolts and U-bolts for secure, straightforward fastening. For example, expansion bolts work well on concrete walls, while U-bolts offer clamps for rails or pipes. Professional setups typically require through bolts for heavy-duty connections and longer lengths to distribute load, such as fixed joints or structural mounts. This mix lets you choose simple anchors for home projects or robust fasteners for larger installations.

Check hole diameter compatibility and fixture fit. The expansion bolt here uses a 10mm hole and a wedge diameter of 10mm, with a nut size of 16x7mm and a washer of 20x2mm, all crucial for proper seating. Materials matter too: zinc plated Q235 carbon steel gives anti-oxidation protection, while stainless steel variants offer higher corrosion resistance. Also confirm the overall length (90mm for the M10x90) to ensure the bolt reaches secure material depth for your mounting surface.

Yes, corrosion resistance is addressed through finishes and material choices. The M10x90 expansion bolt uses a zinc plated finish on Q235 carbon steel, giving anti-oxidation benefits for typical indoor/outdoor use. For higher corrosion resistance in harsher environments, stainless steel options such as U-bolts are available, providing long-lasting performance in metal structures or exterior installations.

Prefer metric sizes like M10x90 or M12 for most masonry and metal mounting tasks, as shown in this range. If you encounter imperial fittings, you may find some items labeled in inches (for example 3/8 inch). Always match the size to the drilled hole, nut, and washer dimensions on your mounting plate to ensure a secure fit and reliable performance.
