I’m really trying not to regret buying all new fasteners for this machine but I’m on the limit of my patience. However much I order there are always sizes and finishes I’m missing and have to buy yet more. I’m reasonable with maths but those better than me can come up with a bottom line figure for the number of possible purchases. These are the permutations.
Required: Bolts + nuts + washers + penny washers + spring washers.
Multiplied by:
Finishes. Some in stainless steel, some in brass (and a few in plain steel as neither SS or brass are available in certain imperial sizes.)
Multiplied by:
Thread types: Whitworth, BSW (British Standard Whitworth) -there is a difference with head size, BSF (British Standard Fine) and where BSW is not obtainable UNC (Unified National Coarse) which mate with most BSW threads albeit technically frowned upon.
Multiplied by:
Sizes: 3/16, 1/4, 5/16, 3/8, 1/2 and 5/8”.
And just to add to my woes I’m having to buy minimum packs of a dozen or so where only a few may be required. When this restoration is finished I’ll have boxes full of now obsolete imperial fasteners I’ll have no further use for.
