The BLOSTM Premium Magnetic Screwdriver Set is number five in this guide: a 42-piece kit supplied in a storage case, priced at £19.49 and rated 4.6 out of 5 from 1,857 ratings. The set name says '(42 Piece)' and the unit count says 42.0, so the headline number is stated twice.

Its own 'What's included' bullet reaches the same figure: 4 cross-head heads, 7 precision screwdrivers, 4 slotted screwdrivers, 1 flexible bit extension, 1 bit holder and 25 extra bits. That is 42, which is more than can be said for the 145-in-1 kit in this guide, where the handle, extension rod, magnetic mat, magnetiser, wrist strap and bag account for 25 of the advertised pieces. Two things still need reading carefully here. First, 25 of the 42 items are bits rather than screwdrivers. Second, the listing contradicts itself on material: the second bullet claims chrome vanadium steel, while the specifications field lists the material as 'Rubber'. At £19.49 for 42 advertised pieces, the price is about 46p a piece, and the rating breakdown shown on the page (76, 16, 6, 1, 1) adds to exactly 100, so those bars read as percentages of the 1,857 ratings rather than as counts. Everything on this page is taken from the Amazon listing for this set, not from any testing of our own.

## Questions people ask

**How many pieces are in the BLOSTM Premium Magnetic Screwdriver Set?**

The listing's own breakdown adds up to 42: 4 cross-head heads, 7 precision screwdrivers, 4 slotted screwdrivers, 1 flexible bit extension, 1 bit holder and 25 extra bits. The set name reads '(42 Piece)' and the unit count is given as 42.0 as well.

**How many of those 42 pieces are bits?**

25 of them. The rest are the 4 cross-head heads, 7 precision screwdrivers, 4 slotted screwdrivers, the flexible bit extension and the bit holder. The storage case is described in a separate bullet and is not part of the 42-piece count.

**What is the BLOSTM set made of?**

The second bullet says it is manufactured using chrome vanadium steel and describes it as stronger than carbon steel. The specifications field lists the material as 'Rubber'. The listing does not reconcile the two.

**Does the BLOSTM 42-piece set include a case?**

Yes. The storage case is described as having a place for every item, so any screwdriver can be found quickly when needed.

**How does the price work out per piece?**

At £19.49 for 42 advertised pieces, that is about 46p a piece. For comparison, the cheapest set in this guide works out at roughly 16p a piece.

**How is the BLOSTM set rated?**

4.6 out of 5 from 1,857 ratings. The breakdown shown on the page — 76, 16, 6, 1 and 1 — adds to 100, so those figures read as percentages of the ratings rather than as counts.
