The STEWART FASTENER 20SSH is an S hook sold in a pack of 100 units. S hooks are open-ended, double-curved fasteners used to connect, hang, or suspend components in a wide range of trade and mechanical applications. They are a standard hardware item carried by HVAC technicians, plumbers, electricians, and general contractors for securing lines, straps, chains, and assemblies. The 20SSH designation identifies this specific hook size within the Stewart Fastener catalog. Each pack contains 100 hooks, making it practical for job-site stocking or bulk service calls.
S hooks in this size range are commonly used in mechanical rooms, utility spaces, and light commercial or residential installations. Typical applications include hanging refrigerant line sets, suspending electrical conduit supports, securing strapping, or organizing hoses and cables. The pack-of-100 format suits contractors who want to maintain a consistent supply without frequent reordering.
Designed as a general-purpose S hook suitable for standard suspension and hanging applications across HVAC, plumbing, electrical, and general mechanical installations.
S hooks are installed by hand and require no special tools in most light-duty applications. Ensure the hook gauge and load rating are appropriate for the intended suspended weight before installation. When used in HVAC or plumbing applications, verify that hook placement does not conflict with local mechanical codes or vibration isolation requirements. Squeeze hook ends closed with pliers where a secure, non-release connection is required.
