Springfast Products
Push Nuts
Push Nuts are high-quality fasteners designed for quick, secure assembly without the need for threads or tools. Made from durable spring steel, these push-on fasteners grip tightly to unthreaded shafts, studs, or rods, providing a strong hold that resists vibration and loosening. Commonly used in automotive, appliance, and industrial applications, Push Nuts offer a cost-effective solution for permanent or semi-permanent fastening where speed and reliability matter.
Flat Round Type
Provides a secure, low-profile hold on shafts or studs, ideal for applications requiring a flush fit
Bolt Retainer
Secure bolts during assembly to simplify installation and prevent loss or misalignment.
Retaining Ring
Snap into place on shafts or in grooves to keep components positioned and prevent lateral movement.
Washer Caps
Washer Caps combine the functionality of a washer with the clean appearance of a finished cap. Designed to snap securely over studs or shafts, they distribute load evenly while concealing exposed ends for a neat, professional look. Made from durable materials and engineered for quick installation, these caps provide both protection and style—ideal for automotive, appliance, and general industrial applications where both performance and appearance matter.
Cage Nuts
Cage Nuts provide a versatile and reliable way to mount equipment in square-holed racks and panels. Each nut is enclosed in a spring steel cage that allows for slight movement, making alignment easy during installation. Designed for strength and reusability, cage nuts are ideal for applications where threaded holes may wear out or where different thread sizes are needed. Commonly used in server racks, enclosures, and industrial assemblies, they deliver a secure, adjustable fastening solution that stands up to repeated use.
U-Nuts
U-Nuts offer a simple, efficient fastening solution that combines the strength of a nut with the flexibility of a spring clip. Shaped like a “U,” they slide easily over panel edges or into pre-punched holes, providing a strong, self-retaining thread for screws or bolts. Designed to resist vibration and eliminate the need for tapping or welding, U-Nuts are ideal for automotive, appliance, and sheet metal applications where speed and reliability are essential.
Lock Washers
Internal and External Tooth Lock Washers provide reliable vibration-resistant fastening by biting into the surface of bolts and mating materials to prevent loosening. Internal tooth washers feature teeth on the inside diameter for use with smaller bolts or screws, while external tooth washers have teeth around the outside for larger fasteners and higher torque applications. Made from durable materials, these washers are ideal for automotive, appliance, and industrial assemblies where secure, long-lasting connections are critical.
T-Nuts
T-Nuts provide a strong, reliable threaded insert for wood, particleboard, and composite materials. Designed with prongs that dig into the material, they create a secure, permanent anchor for bolts and machine screws. Easy to install and built for durability, T-Nuts are ideal for furniture, cabinetry, and industrial assemblies where a sturdy, reusable fastening solution is needed.
