About This Fastener

5/16-18 Grade 2 Square Nuts Plain. While hex nuts remain incredibly popular, you can accomplish a lot with these four-sided internally threaded nuts with flat bottom side and a chamfered, washer-crowned top. Designed primarily for use with square bolts, these nuts take up a larger surface area, which produces more contact with the part being fastened to increase resistance against gradual loosening.

By utilizing these 5/16-18 Grade 2 square nuts, you’ll also be less likely to experience difficulties with loosening. Repeated tightening-loosening cycles can round off the edges of hex nuts, but that won’t happen as quickly with square variations.

You can also use these fasteners in tight spaces and blind spots, such as part of furniture and rail channels.

When you buy from FMW Fasteners, you can customize the quantity of your order, which means you’ll have the perfect amount for a job’s specifications. By optimizing our logistics, you’ll experience less hassle and better shipping, which makes ordering an easy task.

You can benefit from free shipping on qualified orders. Place an order today, and we’ll get you the 5/16-18 square nuts you need!
