Hex Jam Nuts Manufacturer & Suppliers in Ghana & Africa

7 Eleven Baseline Bolts is a hex jam nuts manufacturer and suppliers in Ghana, providing high-quality hex jam nuts for construction, structural, engineering, machinery, automotive, and industrial applications across Ghana and Africa.

How we deliver:

Hex jam nuts are thinner than standard hex nuts, but they maintain the same dimensions across the flats and corners. These nuts are commonly used for two main purposes:

Locking Application – A hex jam nut is threaded onto a bolt and tightened against a standard hex nut. This action locks the primary nut in place and helps prevent it from loosening or backing off.
Leveling Application – Hex jam nuts are also widely used for leveling and adjustment purposes in various mechanical and structural applications.
