Description
Product Overview
The 014973226497 Extruded U Nuts are precision‑engineered fasteners designed for demanding industrial environments. Constructed from high‑grade alloy steel, each nut receives a phosphate coating that enhances corrosion resistance and extends service life even in humid or chemically aggressive settings. The nuts feature a regular 8mm (M8 x 1.25) thread profile with a unified national coarse (UNC) thread type, ensuring compatibility with a broad range of bolts, studs, and threaded components. Packaged in a convenient set of ten, these speed nuts are ready for immediate deployment in assembly lines, maintenance workshops, and field repair operations. Their extruded U‑shaped design provides a secure, self‑locking grip that reduces the need for additional locking mechanisms, while the regular length offers a balanced profile that fits standard clearance dimensions. The product carries the reputable Hard-to-Find Fastener brand, known for delivering reliable fastening solutions across the industrial and scientific sectors. With a best‑seller rank of #56 in Speed Nuts, these components have earned the trust of engineers and technicians who demand consistent performance and ease of installation.
Usage
These extruded U nuts excel in a variety of applications where rapid assembly and dependable holding power are essential. In manufacturing plants, they are commonly used to secure motor housings, gearboxes, and pump assemblies, where the phosphate‑finished surface helps prevent rust during prolonged operation. Maintenance technicians rely on the quick‑install nature of speed nuts to replace worn components on heavy equipment such as compressors, conveyors, and hydraulic systems, minimizing downtime and labor costs. The 8mm size aligns with standard metric hardware, making these nuts ideal for automotive repair shops, aerospace maintenance bays, and marine vessel upkeep where exposure to saltwater and moisture is routine. Additionally, the nuts are suitable for DIY enthusiasts working on home improvement projects that involve metal framing, outdoor furniture, or garden equipment, providing a professional‑grade solution without the need for specialized tools. Their versatility extends to prototype development and research laboratories, where engineers often need a fast, repeatable fastening method for test rigs and experimental setups.

FAQ
What is the difference between a regular U nut and a speed nut?
A regular U nut typically requires a separate lock washer or additional fastening step to prevent loosening, while a speed nut is designed with a built‑in self‑locking feature that allows for quicker installation and reliable retention without extra components.
Can these nuts be used with stainless steel bolts?
Yes, the 8mm thread size is compatible with stainless steel bolts that follow the same M8 x 1.25 specification. The phosphate finish on the nut will not adversely affect the stainless steel material, and the combination provides excellent corrosion resistance.
Are the nuts suitable for high‑temperature applications?
The alloy steel base can tolerate moderate temperature ranges, but for extreme high‑temperature environments (above 200°C/392°F), it is recommended to verify the specific alloy grade and consider heat‑treated fasteners designed for such conditions.
How many pieces are included in the package?
Each package contains ten individual extruded U nuts, providing enough units for small to medium‑scale projects while allowing for easy reordering when inventory runs low.
What is the recommended torque setting for installing these nuts?
For standard alloy steel applications, a torque of 8–10 Nm (Newton‑meters) is generally appropriate for an M8 thread. Always consult the equipment manufacturer’s specifications to ensure optimal performance and avoid over‑tightening.
