They are manufactured using 304 and 316 stainless steel with corrosion-resistant metal substrates and aging-resistant nylon rings. This integrated structure effectively resists rust, salt fog, and chemical erosion in humid and marine settings.
Thin Nyloc nuts are mainly used as jam nuts in double-nut locking configurations or in low-clearance areas with space limitations. Thin Nyloc Nuts meet DIN 439 and ISO 4035 standards and are available in sizes from M4 to M36 (metric) and #6 to 1-1/2″ (imperial).
The flange distributes clamping pressure over a larger surface area to protect soft materials like aluminum, plastic, and sheet metal. The combination of the nylon insert for primary locking and the serrated underside of the flange for friction creates a secure two-in-one locking mechanism.
High-strength Nyloc nuts feature 8.8 and 10.9 strength grade alloy steel substrates with a thickened hexagonal structure for increased tensile strength. Together with a high-toughness nylon ring, they are designed for high-load, dynamic vibration applications such as automotive transmissions and heavy mechanical equipment.
The dense thread pitch of fine thread BSW Nyloc nuts allows for higher assembly precision, a tighter locking effect, and more uniform stress distribution compared to standard threads. This enables micro-adjustments of assembly gaps and reliable anti-loose performance in tight-tolerance machinery.
