Hex head Sems bolts with a captive washer for easier assembly. Metric M6-1.0 thread, 25mm length with a 10mm across-flats head and 17mm washer diameter.


Secure clamping – With Sems captive washer

Sems fastening keeps the washer captured beneath the hex head so the washer cannot fall away during positioning. The captive arrangement relies on a formed washer rim that nests under the head.

Captured washer ensures a consistent clamp surface and reduces lost parts during assembly. Faster, single-handed fitting for repetitive tasks in a workshop or on a car panel.

Reliable replacements – With M6-1.0 metric threading

Thread form follows the M6-1.0 metric standard for compatibility with matching nuts and tapped holes. Consistent thread pitch and diameter ensure predictable torque and engagement.

Straightforward swap-in for existing M6 fittings without trial-and-error. Simplifies repairs by matching common workshop thread sizes.

Fast tool access – With 10mm hex head

Across flats measures 10mm, compatible with standard 10mm spanners and sockets used in most toolkits. Hex head geometry gives positive driver engagement under torque.

Quick tightening and reduced chance of rounding when using the correct spanner. Useful for tight-access assembly where a reliable grip is needed.
