A fastener (14), particularly adapted for use with sheet metal members, comprising an elongated body (15) terminating at one end in a sharp leading end (16) adapted to aid in penetrating sheet metal members. The body (15) is formed with a head (22) at its other end and with a resiliently compressible gripping portion (24) intermediate its ends. The cross sectional area (26) of the fastener (14) adjacent the leading end (16) is smaller than its cross sectional area in the gripping portion (24). The gripping portion (24) may be formed with corrugations (27) on its external surface. The fastener (14) can be driven through sheet metal members and the compressed gripping portion (24) will resiliently grip the metal surrounding the hole formed by the leading edge (16) to hold the fastener (14) in the sheet metal member. |
