Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact thread specification and nylon insert torque retention required by Multiquip equipment assemblies.
• Nylon Insert Locking Design — The nyloc collar grips the bolt thread and resists loosening under vibration — critical on compacting, finishing, and screening equipment subject to continuous mechanical movement.
• Broad Cross-Equipment Compatibility — Verified for use across ride-on trowels (STX55, HTX44, HHN31V, HTN27K, HTN28K, LD60, MD80, MD105), walk-behind trowels (HDA Series, J36, B46, JH90C), screeds (WSHE-A Series, WRS5200), mixers (WM120SH, EM120SM), pumps (MQ62TDD, QP4TKT), and additional Multiquip product lines.
• Consistent Clamping Integrity — Maintains correct bolt preload in assemblies where vibration-induced loosening could cause component misalignment or hardware loss during operation.
• Hardware-Level Stocking Part — A low-cost, high-impact consumable that keeps critical assemblies properly fastened; having 10133 on your parts shelf prevents unnecessary delays during routine maintenance or field repairs.

A nyloc nut — also known as a nylon insert lock nut — is a standard fastening component used throughout construction equipment assemblies to secure components against vibration-induced loosening. The nylon collar inside the nut deforms slightly when threaded onto a bolt, creating a friction fit that holds the fastener in position even under sustained mechanical vibration. When a nyloc nut is damaged, stripped, or missing, the fastened joint can work loose during operation, potentially leading to component movement, accelerated wear on surrounding parts, or hardware loss that compromises machine integrity.
