HSN Hinged Stop Collar with Spiral Nail

• Stop Collars
• 0SO Slip on Stop Collar

The HSN Stop Collar with spiral nail installation is a robust and efficient solution designed for quick and secure fitment in onshore wells. Made from the same high-quality material as Centek’s bow spring centralizers, this stop collar ensures durability and compatibility while enhancing operational efficiency. Its spiral nail locks firmly into internal grooves, securing the stop collar against the casing. This design maximizes annular clearance, reduces rig time, and simplifies installation.

The HSN Stop Collar is a low-profile, cost-effective choice for operators working in less demanding well conditions. Its streamlined design is ideal for applications such as surface casing and vertical sections, making it suitable for standard casing grades. By integrating seamlessly with Centek QA centralizers, the HSN stop collar reinforces Centek’s commitment to providing reliable, efficient, and innovative casing equipment solutions.

Performance ratings

Stop collar performance depends on the ability of the stop collar to hold the centralizer in place. This aids 'runability' and is measured by holding force and integral strength. To help with product selection we've added a rating to all our stop collar products for runability and strength.
