Product Description
M7 × 0.75 Metric Fine Half Lock Nuts – Zinc Plated Brass or Steel
M7 × 0.75 metric fine half lock nuts, available in zinc plated brass or zinc plated high tensile steel. The reduced-height hexagon profile is useful where clearance is limited or where a thin nut is required to lock against another nut.
Also known as jam nuts, these nuts can be tightened against a second matching nut to secure an adjustment. They do not contain a nylon insert or a prevailing-torque locking feature.

Typical Applications
- Locking threaded adjustments with a second matching nut.
- Assemblies requiring a reduced-height nut.
- Maintenance and replacement of M7 × 0.75 fine thread nuts.
- General engineering and workshop repairs.
Fitting Information
Use only with a matching M7 × 0.75 bolt, stud or threaded component. These nuts will not fit standard M7 × 1.00 coarse threads.
When used as a jam nut, tighten against a second matching nut using the appropriate assembly procedure. Use a correctly fitting spanner and avoid overtightening, particularly with the brass option.
Check the nut thickness and spanner size before ordering where clearance or tool access is critical.
