Common questions
Spring washer or nyloc nut?
Both resist vibration loosening. Spring (DIN 127) washers are cheapest and reusable; nyloc nuts give more consistent prevailing torque. We stock both - ask us for the joint.
Do you deliver nationwide?
Yes - we ship to every city and industrial estate in Pakistan by road freight and trusted couriers, with same-day dispatch from Lahore on stock items.
