Hi all, I expect most of you who have been at this a while have a good selection of cap head screws to hand but as a beginner to all this, is it worth buying a mixed selection box of them to start me off. I am going to have a go at the little Wig Wag engine by Ade Swash, or should I just buy what's needed as I need them?

I would buy what you need plus a few extra, if you buy a selection box you could end up with bolts and screws you may never use.

Really depends if you may use them again , i use them all the time so the assortment i bought has served me well and i just top up what I’m running low on . A word to the wise is the cheap assortments are just that cheap junk so look for quality name brand fasteners - the set i bought here in Australia were all unbrako so are of decent quiality . You could of course do it the other way and build up your set as you need them but do yourself a favour and don’t skimp on quality !

My approach is to do both:
As is often the case in engineering, it's a matter of striking a balance. My work requires a relatively small range of metric fasteners, which I stock by the hundred and steadily use up. I have the moderate storage space and cash needed to do this. I'd buy differently if I did one-offs involving a wide range of different fasteners and was on a tight budget in a tiny workshop.

Dave, which ever way you buy them get decent quality, the cheap ones can be rubbish, also a quality set of keys.
Just a thought Dave but apart from cap heads probably fixing the base to the vertical column the Wig Wam doesnt have any other cap heads does it..? or are you thinking for general use..?

Hi Ron, just for general use really. I think as a couple have suggested I will start by buying a few more of what's needed at the time and build up an assortment that way.

Thats what I do Dave, we have a local supplier who will sell you 1 screw but I go and get what I need at the time and round the qty up.

I’ve got quite a large selection of socket screws in stock. I used to buy locally but I find it’s just as easy to buy on the auction site. I always get more than I need for a given project if I need to buy anything.
Nearly everything I buy in the way of fasteners is stainless these days, I hate stuff going rusty.

I avoid buying fastenings from the local hardware shop, the little blister packs tend to contain rather low quality no name stuff. they are also rather expensive. The better way is to purchase fastenings from an industrial supplier. small fastenings come in various box quantity lots starting at 100. Often a whole box will cost significantly less than a few fasteners in blister packs. If you google Industrial fastenings for your town or city you may be surprised how many there are.
This UK company popped up in a google search I do not know them at all however the website is easy to use as a reference point.
I am sure the members of the forum will have other options.

When I started I bought mine by the box. Twelve years on a couple of the boxes are almost empty so it wasn't an extravagance at all. M4 mostly plus some M3 and M5, cap heads and countersunks.

Like everything else it depends on intended usage but for my messing about I usually buy stainless capheads from ebay. I have a whole selection of sizes and lengths from my r/c heli days as a staring point and top up + extras in the sizes I need. Obviously for high tensile situations (which rarely apply to me ) I use that type of caphead instead.
If in doubt get them longer and can always be trimmed down.

Buy your Capscrews from a proper engineering supplier. "supermarket" hardware can be low strength. Unbrako is good quality. (Ditto for Allen keys, I still use the Unbrako Allen keys bought in 1958 when I was was an Apprentice )
The steel in the D I Y screws and keys can be soft and more trouble that they are worth. You tend to find this out when you need to remove a tight screw!

Where abouts do you live, one of us might be near by and could tell you where to shop.

Dave - I usually buy a box or two when either Aldi or Lidl have them in. I have not seen any lately though. To be sure, they are not as good as something like Unbrako but they are quite acceptable for much of what I do in the workshop. I would not use them though on safety critical fittings - on a motor bike for instance.

If you want to buy online, iv’e used Orbital fasteners in the past, found them good quality and reasonably priced.

Always try and buy cap head screws with the "DIN 12.9" spec to ensure the quality. No guarantee but should be better.

Quality of items bought on EBay can be very variable, have found a good supplier online where quality is excellent and small quantities is no problem. The company is called Westfield Fasteners and they carry a good range of sizes and types and their stainless fasteners are excellent.
