Value Collection BDNA-24111 Worm Gear Clamp Sae 8

Product Description

The VALUE COLLECTION BDNA-24111 is a worm drive hose clamp rated SAE Size 8, designed to secure hose and tubing connections across a wide range of trade and light industrial applications. The stainless steel band measures 5/16 inches wide and adjusts to fit diameters from 1/2 inch up to 29/32 inch, making it a reliable mechanical fastener for hose-to-fitting joints. The worm drive mechanism allows precise tightening with a standard screwdriver or nut driver, providing consistent radial clamping force without the risk of over-slip. Plumbers, HVAC technicians, and general trade professionals commonly install these clamps during new construction and service work.

This clamp is suited for residential and light commercial plumbing, HVAC ductwork connections, coolant lines, fuel lines, and other fluid-handling assemblies where a secure, corrosion-resistant band clamp is required. The SAE 8 designation standardizes the size range, allowing straightforward selection when replacing worn or damaged clamps on existing installations. The stainless steel construction holds up well in wet or humid environments typical of mechanical rooms, crawl spaces, and rooftop equipment installations.

Key Features

• Worm drive mechanism for precise, tool-assisted tightening with a screwdriver or 5/16-inch hex driver
• SAE Size 8 rating covers diameters from 1/2 inch to 29/32 inch
• Stainless steel band resists corrosion in wet and humid service environments
• Band width of 5/16 inches distributes clamping load evenly around the hose
• Compact, low-profile design fits into tight installation spaces

Compatibility

Designed as a standard SAE 8 worm gear clamp suitable for hoses and tubing with outside diameters between 1/2 inch and 29/32 inch across plumbing, HVAC, and general mechanical applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified mechanical tradespeople. Before servicing any hose connection, shut off fluid supply and relieve system pressure. Slide the clamp onto the hose before seating the hose fully onto the fitting, then position the clamp over the retaining bead and tighten the worm screw evenly. Do not overtighten, as excessive force can cut into the hose wall and cause premature failure.
