Tall Nylon Insert Hex Lock Nuts — DIN 982

FULLERKREG DIN 982 High-Type Nylon Insert Lock Nuts (also known as Tall Nyloc Nuts or Type P prevailing torque nuts) feature a full-height hexagon body with an integrated polyamide insert that locks onto the bolt thread under compression, providing reliable vibration resistance without adhesives or secondary locking devices. Available in four material grades to suit every application environment — from general construction to marine offshore. All grades conform to DIN 982 / ISO 7042, covering thread sizes M5 through M24.

Standard Overview — DIN 982 / ISO 7042

DIN 982 specifies prevailing torque hexagon nuts with a non-metallic insert — high type (Type P). The standard covers metric thread sizes M5 through M24 across property classes 4, 6, 8, and 10. DIN 982 has been superseded by ISO 7042, but dimensions remain fully interchangeable. The high-type (DIN 982) provides greater nut height and higher prevailing torque than the low-type (DIN 985 / ISO 10511), making it the preferred choice for heavy vibration and high-load applications.

• ✅ Thread range: M5 – M24
• ✅ Standard: DIN 982 / ISO 7042
• ✅ Nylon insert: Polyamide PA6 (max 120°C continuous)
• ✅ All grades RoHS compliant
• ✅ Mill certificates & inspection reports available on request
