BigHeads
were originally designed for the plastics moulding industry.
Their unique perforated design allows plastics, composites
or adhesives to flow through their mild steel or 316S11 stainless
steel heads during moulding. This locks them into virtually
any plastic product and efficiently spreads the applied dynamic
loads over the widest possible area. BigHeads can also be surfacemounted
on to metal, wood, glass, brick, composites or laminates, using
modern adhesives or rivets, screws or spotwelds. No expensive
drilling, filling or �making good� is needed, and labour costs
are therefore reduced to a minimum. |

Understanding the BigHead part number
There are 2 types of BigHead fasteners � male and female. The first letter in the BigHead part number is either M (male) or F (female). A typical part number, M1/B38-M6x25, is a male fastener with a 38mm dia. head, with an M6 threadform stud 25mm long. |

For female versions, heads are either B- or S-. B is Blind, with no central hole; S is Sighted, with a central hole. The part number F2/B38-M6x12 is a female fastener with a 38mm dia. blind head, and an M6 internally-threaded collar 12mm long; with a central hole it would be F2/S38-M6x12. The part number F1/B38-M6 is again a female fastener, but using an M6 hex nut. |

For stainless steel versions, each part number start with 316 (we always use 316S11 marine grade stainless steel). A 316-M1/B32-M6x12 is a stainless male fastener with 32mm square head, and an M6 stud 12mm long. A 316-F2/S32-M6x10 is a female stainless, with central hole and a 10mm M6 collar.
