so nylock and nylon lock are the same thing?

[saunixcomp]

@adamcreveling Not sure if there's a specific situation you are referring to, but yes, i would guess that nylock is an abbreviated term for nylon lock

hey im newb at this like i dont know anything about bolts but im suppose to fix something but the nylon locknut doesnt even go in the full screw and the part is always loose how im suppose to tighten it ?

[saunixcomp]

@jHavoc696 Not sure what to tell you. If it's the correct thread count for the bolt, then the nut should tighten with a wrench.

Thanks for the video. Just a small issue, the castle/castellated nut is actually a slotted nut.

[saunixcomp]

@Mavermick1 Is it? google image would disagree..  What's the difference?

[rkward101]

@saunixcomp I don't think there is a difference, you just don't hear it as often anymore.

[tundragriz]

Instruction concerning torque needs to mention that a torque wrench must be stored at its minimum setting. Stored at minimum the calibration will not change over time. Storing it under tension will alter the springs force over time, it is calibrated from its initial tension. It should be set to specified value, used, and reset to minimum. Should also never be used for loosening, loosening torque tells nothing and can damage the wrench.

this is NUTS !

@saunixcomp - Hi. To look at a slotted nut it just a normal hex nut with slots........whereas on a castellated nut, the slotted section is circular. I think the terms are often intentionally combined now, but that is the original definition given to me.
