Video Transcript for Review of ABS Fasteners Trailer Leaf Spring Suspension - Nylock Nut - 6-112

Jeff Hello everybody. This is Jeff at Today, we're gonna take a look at this zinc plated nylon locknut for one inch diameter suspension bolts. Now, this nyloc locknut will secure a suspension bolt on your trailer. This one is designed to work with the trailer suspension bolts part number 7-169, 7-182, or 7-136-2. All three of those are sold separately on our website and they are listed on this product page as a related product.

If you notice, this is a nyloc nut and what that means is it has this nylon collar right here on the end of the nut that'll deform over the threads of the bolt as that bolt is tightened down. And it's increased friction on the threads of the bolt will lock the nut to the bolt. The bolt, or the nut itself is a zinc plated, which is corrosion resistant. Again, it is a one inch diameter. And show you with the ruler here, if you go in the inside, you can see there's your one inch diameter.

It does use eight threads per inch, and it is for a quantity of one locknut. But that should do it for the review on the zinc plated nylon locknut for the one inch diameter suspension bolts..

Locknut for Suspension Bolts - 1" Diameter - Zinc Plated - 6-112

Average Customer Rating:  4.6 out of 5 stars   (8 Customer Reviews)

1" Diameter locknut is designed for use with trailer suspension bolts (7-169, 7-182, or 7-136-2 - sold separately).


The first order was great. The second we were missing half of the order. We are missing one U-bolt with nuts, four U-bolt nuts for the U-bolts that were in the package and we are missing both 1" eye bolts and nuts.





Service is excellent

  • Should Shackle Bolts Be Tightened Down So There Isn't Any Play
    It sounds like you have an equalizer bolt like part # 7-136-2-6-112 as opposed to one with a hex head like the part # 7-169-6-112. This is fine as long as the diameter and length matches what you're needing. When installing suspension bolts on your trailer we don't have any torque specs for them. You'll want to snug them up so the equalizer and shackles don't have side to side play and then back the nut off 1/4 turn so that there is some movement in the suspension but not too much. If...

  • Replacement Leaf Spring Bolts and Bushings for Dexter 10K Axle On Big Tex Trailer
    The correct replacement leaf spring bushings for any given trailer will be dependent on the width and type of the leaf springs. The most common for a Dexter 10,000 lb Trailer Axle are 3" wide slipper springs. If you have 3" wide slipper springs then you can use part # 14-69. Then for eye bolts you can use part # 7-136-2-6-112 or part # 7-169-6-112 if you have 3" wide slipper springs. That said, it is always best to measure your leaf springs bushings and eye bolts in order to determine...

  • Where To Measure Equalizers To Determine Correct Replacement For 2018 Kaufman Flatbed Trailer
    I would be happy to help you determine the correct replacement equalizer for your 2018 Kauffman flatbed trailer, but unfortunately we do not have a break down of the specific components your trailer uses. Instead you will need to measure your current equalizer center to center of the two horizontal mounting holes, and from the center of the upper hole to the center line of the two horizontal holes. For example the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 5-3/4" Long - 9/16"...

  • Installation Instructions for Equalizer for Slipper Springs
    You will want to use a 1" diameter wet center equalizer bolt like # 7-136-2-6-112 which inserts in the center hole and bolts to the hanger. I have attached a helpful article about the Slipper Spring Trailer Suspension System. The equalizer section is about halfway down the page.

  • Wet Suspension Bolts and Bushings for 7K Axles with Slipper Spring Leaf Springs
    It looks like the slipper springs for 7,000 pound axles are 2 inches wide which is good because that is a very common size for slipper springs so there will be options available. We have a 3-5/16 inch long wet bolt in a 9/16 inch, # 126B2, but I do urge you to first check to see if that 3-5/16 inch length will be long enough compared to your existing bolts. You may not need any new bushings but if you do then you would want to look at the inner and outer diameters of the bushings you...

  • Recommended Hardware for Dexter Equalizer for 2-1/2" Wide Slipper Springs # 13-141-3
    To use with the Dexter Equalizer for 2-1/2" Wide Slipper Springs # 13-141-3 I recommend using the 1" diameter Suspension Bolt # 7-136-2-6-112 for the center/hanger bolt and the 3/4" diameter # 126A1 for the spring bolt. Both options are wet bolts with integrated grease zerks to allow for easy maintenance.
