Macro-mechanical • Bonding using surface irregularities where surface roughness can be seen or felt. • Screws, nuts, bolts, glues join two pieces of woods • In dentistry- cementation of crown or bridges to teeth with ‘non adhesive cement’ • Disadvantage- stress is concentrated in the vicinity of the fastener
