Hillman Fasteners 829716 Nylon Insert Lock Nut 10-24 Ss 100pk

Product Description

The HILLMAN FASTENERS 829716 is a nylon insert lock nut designed to maintain clamping force in assemblies subject to vibration, thermal cycling, or repeated loading. The 10-24 coarse thread pattern fits standard machine screws and threaded rod used across HVAC equipment, electrical enclosures, and general mechanical assemblies. Constructed from stainless steel with an integrated nylon insert collar, this nut resists corrosion and provides consistent prevailing torque without adhesives or secondary locking hardware. Sold in a 100-count box, it is a practical stock item for service vans, maintenance shops, and contractor supply rooms. Electricians, HVAC technicians, and plumbers reach for this hardware when securing panels, brackets, and equipment housings in both indoor and outdoor environments.

The 829716 lock nut is suited for light commercial and residential applications where corrosion resistance and reliable thread locking are required. Its stainless steel construction makes it appropriate for damp or humid environments such as mechanical rooms, rooftop equipment installations, and exposed outdoor enclosures. The nylon insert engages after the nut is fully threaded, creating a friction lock that resists loosening without damaging the mating thread.

Key Features

• 10-24 coarse thread sizing for compatibility with standard machine screws and threaded rod
• Stainless steel construction for corrosion resistance in wet and outdoor environments
• Nylon insert collar provides prevailing torque locking without adhesives
• 100-count pack reduces per-unit cost for high-volume service and maintenance work
• Reusable fastener design maintains locking performance across multiple installations

Compatibility

Designed as a standard 10-24 nylon insert lock nut for use with any 10-24 machine screw or threaded stud in HVAC, electrical, plumbing, and general mechanical applications.

Installation Notes

Installation requires a standard hex wrench or nut driver sized for the 10-24 nut across flats. De-energize electrical equipment and shut off mechanical systems before accessing fastener locations inside enclosures or equipment panels. Do not exceed the rated torque range for stainless steel fasteners of this thread size, as overtightening can deform the nylon insert and reduce locking effectiveness. The nylon insert is rated for normal service temperatures only — verify suitability before installing near high-heat sources such as heat exchangers or flue assemblies.
