Hayes and Yeading United have signed strikers Nicholas Bignall and Tom Derry.
Bignall, 24, joins from Conference South rivals Sutton United, having ended last season at Basingstoke.
While on the books of hometown club Reading, he spent a brief loan spell at Brentford in 2011 but failed to score in seven appearances.
However he did score twice in four Championship games for the Royals, and netted during loans at Northampton, Cheltenham and Stockport.
Derry, 19, was released by Conference Premier side Aldershot this week, having previously been at Gillingham and Charlton.
He had loan spells in Conference South at Chelmsford City and Eastbourne Borough before joining the Shots.
