Description

DESCRIPTION

Nyloc Hex Nut - High Tensile - Mechanical Galvanised - M30 (Box=25)

(Price per unit)

Nyloc Insert Nuts feature a nylon ring at the top of the nut that locks onto the bolt threads once fully tightened. This creates a friction-based locking action that helps prevent loosening due to vibration, removing the need for a separate lock washer.

  • Nylon insert grips the bolt threads when the nut is seated
  • Locking action is based on friction, not additional hardware
  • Helps resist loosening under vibration and movement
  • Designed for single-use applications

The nylon insert deforms during the first installation, which means its locking effectiveness is reduced if the nut is reused.

Nuts should be selected to match a compatible bolt grade and material system to ensure proper strength and performance.

Heat Tolerance.  For high temperature applications, ie above 120 °C , use an all metal locking nut, (e.g. Stover, Conelock, K-Lock) which does not have nylon and is rated to the same temperature as the steel itself.

Recommended use:
Standard open-air finish for timber framing, fencing, decking, retaining walls, and applications involving treated timber contact (H3 and H4 treated pine). Provides longer lasting corrosion protection in most outdoor and agricultural type environments.

Also known as: Nyloc Nuts, Nylon Insert Lock Nuts, Nyloc Insert Nuts, Self-Locking Nuts (Nylon), Polystop Nuts

Finish

MECHANICAL GALVANISED
 
MGAL provides better abrasion resistance than HDG and does not introduce any risk of hydrogen embrittlement. MGAL products provide similar corrosion resistance to HDG.
 
A nut with a mechanically galvanised coating is typically used anywhere you need a corrosion-resistant fastener, but not necessarily the heavy-duty thickness of hot-dip galvanising.
