Help! What Are These Called?

[drewllly]

Hi, I'm working on a series of hanging sculptures, and need to buy some more of the screws/bolts shown in the picture. Does anyone know what type they are or what I could search for? Obviously searching for "bolt" or "screws" isn't going to be much use!

Cheers

or sometimes, inaccurately, a Chicago rivet, screw or nail, (used e.g. in repair of leather binocular case straps and hinges)

Sleeve Expansion Anchor Bolts and Sleeve nuts are the name of this type of screws.

Sleeve bolts, you can get them at a lot of online stores. One of the best places probably being eBay...
