The VALUE COLLECTION A410306 is a nylon insert hex lock nut manufactured from Grade 316 A4 stainless steel with an uncoated finish. It features an M12 x 1.75 right-hand thread and conforms to DIN 985 standards. The nylon insert provides consistent prevailing torque, resisting loosening caused by vibration and thermal cycling without requiring a separate locking device. At 12.00 mm in height with a 19.00 mm width across flats, this nut seats with standard hex tooling. Each package contains 25 pieces. It is suited for mechanical assemblies, plumbing, HVAC mounting hardware, and marine or corrosive-environment fastening applications where stainless steel fasteners are specified.
Grade 316 A4 stainless steel provides elevated corrosion resistance compared to 304-series fasteners, making this nut appropriate for outdoor, marine, coastal, chemical-exposure, and wet-service installations. The DIN 985 dimensional standard ensures interchangeability with other DIN-compliant hardware. Trade professionals in plumbing, HVAC, electrical, and general mechanical contracting use this fastener wherever a secure, reusable locking nut is required on an M12-threaded fastener.
Designed for use with M12 x 1.75 right-hand threaded bolts, screws, and threaded rod conforming to DIN or metric standards. Suitable as an OEM-style replacement or new-installation fastener wherever a DIN 985 nylon insert hex lock nut is specified.
Install and torque with a standard 19 mm hex wrench or socket. Nylon insert lock nuts are generally suitable for single or limited reuse; inspect the nylon insert for wear or deformation before reusing. Ensure the mating threaded fastener is clean and free of damage before assembly. Follow applicable mechanical and structural codes for the specific installation environment and load requirements.
