About This Item
The Pentair Clamp Bolt (24850-0010Z) is the OEM replacement clamp bolt for the Sta-Rite System 3 series of D.E., Sand, and Modular Media filters. This is a single-bolt listing — the number of bolts required per filter varies by model (see table below).
⚠️ IMPORTANT: QUANTITY REQUIRED VARIES BY MODEL
The number of clamp bolts required per filter depends on your specific model. The S7-series filters (S7D75, S7M120, S7M400, S7S50) use seven bolts; the S8-series filters (S8D110, S8M150, S8M500, S8S70) use eight bolts. This listing is for one (1) bolt. Order the correct quantity for your model before beginning service.
The tank clamp bolt secures the filter tank clamp band that holds the upper and lower tank halves together under operating pressure. A damaged, corroded, or stripped clamp bolt compromises the integrity of the tank seal — replacing worn bolts at the first sign of corrosion or thread damage restores the clamping force needed to maintain a leak-free filter housing.

Pro Tip
When replacing a damaged clamp bolt, inspect all remaining bolts on the tank band at the same time — corrosion and thread wear typically affect multiple fasteners simultaneously on older filters. Count the total bolts on your existing clamp band before ordering to confirm whether your model uses seven or eight, and order the full set to complete the service in one visit.
