Spuhr Clamping Screws for SA/ST-series

• Direct fit for SA/ST mounts: These clamping screws are made specifically for Spuhr SA and ST-series mounts, so they restore the original side-clamp function without trial-and-error on thread size or length.
• M5x25 Torx 20 format: The M5x25 dimensions and Torx 20 drive give a secure interface during installation, helping reduce cam-out and making controlled tightening easier.
• Steel construction: A steel screw is suited to repeated mount service and clamp tension, giving the side-clamp assembly the strength needed for dependable optic mounting.
• Purpose-built mount maintenance part: As a dedicated replacement component for scope mount side clamps, this accessory helps keep compatible Spuhr mounts in service instead of replacing the complete mount.

About the Spuhr Accesories Series

Spuhr Accesories are built around the company’s modular mounting concept, with add-ons and replacement parts designed to work directly with ISMS scope mounts and related mounting systems. The series covers practical interface components rather than generic hardware, so each part is intended to solve a specific mounting or accessory-fit task in a precise way. Within the range are direct-interface adapters, spacers, Picatinny sections, ACI interfaces, sight-specific mounts, and small service parts that keep existing mounts working as intended.

A defining feature of the series is the Spuhr Interface, which uses two threaded holes with dual conical parts to create a repeatable and secure attachment point for compatible accessories. That system supports a wide variety of equipment, including backup sights, lasers, illuminators, angle cosine indicators, and night-vision mounting solutions. In practice, the series is aimed at shooters who want a mounting setup that stays organized, adaptable, and easy to maintain. Small parts such as replacement screws matter in that context because they preserve the function and clamping integrity of the mount rather than forcing a full replacement when a single wear item is needed.

About the Spuhr Clamping Screws for SA/ST-series

The Spuhr Clamping Screws for SA/ST-series are a dedicated replacement set for the side-clamp system used on SA and ST-series mounts. Their role is straightforward but important: they provide the clamping force that secures the mount to the rail, so using the correct screw pattern is essential for maintaining proper fit and repeatable mounting performance. Because these screws are made in the correct M5x25 Torx 20 format, they match the intended geometry of the clamp assembly instead of relying on a close substitute that may not seat or tension correctly.

The practical advantage of a purpose-built replacement part is consistency. A side-clamp screw is not just general workshop hardware; it is part of the mount’s retention system, and the right dimensions help the clamp engage as designed. The Torx 20 drive supports positive tool engagement during installation, which is useful when servicing a mount in the field or on the bench. The steel construction is also appropriate for a component that must handle repeated tightening and loosening while maintaining strength. For shooters maintaining an existing Spuhr mount, this accessory is a simple way to return the mount to proper working order with the correct hardware for the SA/ST platform.
