In the field of concrete form accessories and rigging hardware, reliable connectors are essential. At H&F, we supply a broad range of trusted products — including spring hooks, carabiners, quick links, and bolt snaps — sourced from certified manufacturers. Our commitment is to quality control, practical service, and customer satisfaction, offering free samples, personalized support, and door-to-door delivery to clients worldwide.

Spring Hooks: Versatile Quick-Connect Clips

Spring hooks, often referred to as snap hooks, are simple yet effective connectors featuring a spring-loaded gate that automatically closes. Typically made from carbon steel or stainless steel, these hooks are often finished with galvanizing or zinc plating for additional corrosion resistance. Stainless steel versions naturally resist rust without extra coatings and offer higher load capacities.

The design is straightforward: a curved hook with a spring gate on one end and, optionally, a fixed eyelet on the other. Variants include no eyelet, with eyelet, screw nut & eyelet, screw nut no eyelet, oblong, and oval forms. Users depress the gate to insert a rope, chain, or fitting, and the spring snaps shut to secure the connection. With an average load-bearing capacity suitable for medium-duty tasks, spring hooks are commonly found in scaffold safety systems, tie rod attachments, and outdoor rigging. Some designs integrate locking mechanisms for enhanced security, making them indispensable where quick, temporary connections are needed.

Carabiners: High-Strength Safety Connectors

Carabiners are heavy-duty connectors, initially developed for mountaineering but now widespread in construction and rigging industries. They are usually crafted from aluminum alloy or stainless steel, offering a balance between weight, strength, and corrosion resistance. Common styles include asymmetric D-shape, pear shape, D-shape, and oval carabiners, each optimized for different load distributions.

Carabiners can be classified as non-locking or locking types. Locking carabiners use mechanisms like screw-gate, twist-lock, or auto-lock systems to prevent accidental gate opening, which is critical in high-risk environments. Certified models comply with international standards like EN 12275, EN 362, and in some cases, UIAA ratings. Load capacities vary but often exceed 20 kN on the major axis, making them suitable for attaching lifelines, hoisting equipment, or securing safety harnesses. Innovations such as snag-free Keylock designs further enhance usability by preventing the gate from catching on other equipment.

Quick Links: Secure Screw-Link Connectors

Quick links, or screw links, provide a solid and secure connection through a threaded nut closure. Manufactured mainly from galvanized carbon steel or stainless steel, they are available in various shapes, including oval, delta, and D-shape designs. Unlike spring hooks, quick links require manual tightening and often tools for secure closure, ensuring the link remains firmly locked under tension.

They are particularly useful in static load applications, such as securing tie-downs, linking slings, or connecting rigging assemblies in concrete formwork. Stainless steel quick links are especially favored for their resistance to corrosion in harsh environments. While they are incredibly strong — with working load limits often exceeding 1.5 tons for mid-sized links — they are generally not rated for dynamic overhead lifting or life-support applications. Nevertheless, for fixed anchoring purposes, quick links offer an excellent combination of strength and reliability.

Bolt Snaps: Reliable Fastening Clips

Bolt snaps are versatile clips equipped with a spring-loaded sliding bolt that ensures a secure closure. Users operate them by pressing a small button, retracting the bolt to open the hook, then releasing it to automatically snap closed. Bolt snaps come with either fixed eyes or swivel eyes, allowing attached lines or straps to rotate freely and reduce twisting.

Constructed from durable materials like brass or stainless steel, bolt snaps are ideal for moderate load applications where frequent attachment and detachment are necessary. Common in scaffolding safety gear, tool lanyards, and outdoor equipment, bolt snaps are designed to prevent accidental openings even in challenging environments. Variations like double-ended bolt snaps and different eye designs (square, round) provide options to match specific operational needs.

Забезпечення якості та сертифікація

Every product supplied by H&F undergoes rigorous quality checks before shipping. Our manufacturing partners operate under ISO-certified quality management systems, and critical products are individually proof-tested for load performance. Many connectors meet or exceed standards such as EN, ASTM, and DIN specifications, ensuring consistent reliability.

Surface treatments like hot-dip galvanizing, electroplating, or passivation are inspected for thickness and uniformity, safeguarding against premature corrosion. Whether in demanding construction sites, marine applications, or outdoor projects, our connectors are built to withstand real-world conditions without compromise.
