Description

This 16-pack contains premium stainless-steel bolts paired with nylon-insert locking nuts (Nyloc), offering a secure, corrosion-resistant fastening solution for castors, equipment bases, frames, trolleys or conveyor feet. The stainless-steel bolts and Nyloc nuts deliver strong load-bearing and vibration-resistant performance — ideal for demanding industrial, commercial, food-processing, marine or hygiene-critical environments.

The nylon insert in each nut grips the bolt thread tightly, preventing loosening under vibration or movement. This makes the set particularly suitable for applications where castors or equipment will undergo frequent motion, load shifts or are exposed to moisture, chemicals or wash-down processes.


Key Features

  • Stainless-steel bolts and nylon-insert (Nyloc) nuts for corrosion resistance and durability

  • Bolt size: M12 × 40 mm — versatile for castor mounting, equipment feet, frames, racks and structural assemblies

  • Nylon insert locking nut provides a secure, vibration-resistant fastening that resists loosening under dynamic loads 

  • High-strength fastener set suitable for heavy-duty use and repeated assembly/disassembly cycles

  • Ideal for wash-down, damp, marine, industrial or hygiene-sensitive environments where corrosion resistance is a must


Specifications

  • Bolt Thread Size: M12

  • Bolt Length: 40 mm

  • Nuts: Nyloc (nylon-insert locking nuts) — stainless steel construction with nylon locking insert for vibration resistance 

  • Pack Contents: 16 bolts + 16 nyloc nuts

  • Material: Stainless steel bolts and nuts (typically A2 / 304-grade or equivalent corrosion-resistant grade) 

  • Intended Use: Securing castors, conveyor/bench feet, structural frames, trolleys, racks, equipment bases


Applications / Industries & Environments

This bolt and Nyloc nut set is well suited for:

  • Mounting castors on trolleys, carts, benches or racks in warehouses, workshops or food-service facilities

  • Securing equipment bases, stainless-steel frames or conveyor feet in manufacturing, processing, medical or industrial environments

  • Marine and outdoor installations — stainless steel resists rust and corrosion even in wet, salty or harsh conditions 

  • Food processing, pharmaceutical, laboratory or clean-room applications — stainless fasteners withstand frequent cleaning, moisture and hygiene requirements

  • Any mechanical assembly subject to vibration or movement, where locking nuts help prevent loosening over time
