1/4 Finish Nut
The 1/4 Finish Nut is an essential industrial fastener providing a secure and reliable connection when paired with a matching 1/4 inch bolt. Engineered from high-quality steel, these nuts are ideal for a wide range of MRO, construction, and fabrication projects requiring dependable performance.
- Industrial Grade Steel
- Meets SAE J995 / ASTM A563
- MRO & Fabrication Fastening
- 1/4 Inch Nominal Diameter
Our 1/4 Finish Nuts are manufactured from quality carbon steel to meet the stringent mechanical and material requirements of SAE J995 and ASTM A563 standards. These specifications govern proof load, hardness, and material composition, ensuring compatibility with corresponding graded bolts (such as Grade 2 or Grade 5). This technical compliance guarantees consistent clamping force and reliable performance in demanding industrial environments. The standard hexagonal shape allows for easy installation and tightening with common tools, making it a versatile component for any hardware inventory.
Designed for versatility, these industrial-grade finish nuts are indispensable for general-purpose fastening across numerous applications. They are commonly used in machinery assembly, equipment repair, structural framing, and automotive maintenance. Their primary function is to secure a bolt or screw, preventing loosening due to vibration or load. Whether for large-scale construction hardware needs or routine MRO supplies, the 1/4 Finish Nut provides a strong, simple, and cost-effective solution for joining metal, wood, and other materials in the Los Angeles industrial market.

Finish Options
Our 1/4 Finish Nuts are available in several common finishes to suit different environmental and aesthetic requirements. Standard options include Zinc Plating for good corrosion resistance in mild environments, Hot-Dip Galvanizing for superior protection in outdoor or harsh conditions, and a Plain (oiled) finish for applications that will be painted or welded.
How to Measure
To ensure you order the correct nut, specify the nominal thread diameter, threads per inch (TPI), and the required grade. The grade of the nut should always match or exceed the grade of the bolt it is being used with for a secure connection.
Example: '1/4-20 Grade 5 Hex Finish Nut, Zinc Plated'. This specifies a 1/4 inch diameter, 20 threads per inch, Grade 5 strength, and a zinc-plated finish.
