  • Premium Strength: Manufactured from Grade 8 hardened steel for superior durability and high-torque applications
  • Course Threaded: Designed with a course thread for a more secure attachment between pieces. Compatible with standard nuts and washers.
  • Hex Cap Construction: These large bolts feature a hex cap that allows for greater torque application than circular caps
  • Large Hex Bolts: The greater diameter of these steel hex bolts allows for stronger, more heavy-duty load bearing across the join

Description

Ensure your projects are completed with high quality fastenings from Hard-To-Find Fastener. These grade 8 course threaded hex bolts are ideal for automotive, industrial, and heavy machinery projects requiring maximum fastening security. Designed with a course thread for a more secure attachment between pieces, these large bolts feature a hex cap that allows for greater torque application than circular caps. The greater diameter of these steel hex bolts allows for stronger, more heavy-duty load bearing across the join. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed building or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.

Much better than visiting my local hardware, or big box store
Size: 1/4-20 x 1-1/4
Exactly what I needed. Admittedly, I was skeptical of getting decent quality, but these are anything but cheap quality. I am very impressed with them and highly recommend the bolts to anyone looking for grade 8 with perfect fit and without imperfections. Even though it is only a preference, I think the yellow sheen dresses up my project. These deserve the full 5 stars. ... show more

Easy to grip with socket/wrench
Size: 1/4-20 x 3/4
These screws were a perfect match for the screws I removed from my transaxle except the head-much better. I was able to replace using a drill. The old screws were torx head and needed to be grinded down. I have a few projects that I will be using these to replace those screws. Good quality, bargain, and find. ... show more

High quality bolt.
Size: 1/4-20 x 2
They are just grade 8 bolts but damn they look good with that nice gold finish. Don't know how long that finish will last but they look like a well made piece packed in a box and delivered in a few days. My application didn't require a lot of torque so I can't speak for strength. Highly recommend.

A good deal on a harder-to-find size
Size: 1/4-20 x 1-3/4
I wouldn't want to bet a lot on these bolts being true USA Grade 8 spec, but because I paid a Grade 5 price for them, I don't mind. Most of my projects need only Grade 3 or maybe Grade 5 hardware anyway. The 1-3/4" length (in any grade) is not available in any local hardware store. The local 1/4-20 bolts jump from 1-1/2" to 2". So this purchase lets me fill the nearly-empty 1-3/4" bin in my hardware cabinet. ... show more
