## Before you buy

- The listing describes the material as 304 stainless steel in its title and feature copy, while the technical material field says only stainless steel. Confirm the precise grade if 304 is essential. The finish is also described as both Plain and Polished in separate listing fields, so the actual finish is unclear. The title and details identify a 150-pack, while feature text claims a storage box without a formal package inventory.

## A good fit for

- People needing \#6-32 UNC nylon insert lock nuts for a compatible bolt.
- DIYers or repair users who want a multi-piece supply for replacement fasteners.

## Less suited to

- Buyers whose bolt requires a thread size other than \#6-32 UNC.
- Projects that require a verified stainless grade or definite surface finish before purchase.

## Customer feedback

Customer feedback describes these as inexpensive jam nuts that work for their intended purpose, with positive mentions of value and functionality. That is relevant for routine \#6-32 replacement work, but it does not establish fit for every application or independently confirm the listed material grade and finish. The aggregate ratings are mostly five-star, though a smaller spread of lower ratings means experiences are not uniform.
- Positive themes: Customers describe the nuts as good value and say they work for their intended purpose.
