Screwdriver Sets.

What are Screwdriver Sets?

A screwdriver set, also known as a set of screwdrivers, supplies a graded group of drivers in a single collection and sits alongside individual drivers in Accu's screwdriver range. Each set holds blades of matched materials in ascending tip sizes, presented in a roll, rack or case that keeps the sizes ordered and visible.

Buying the group rather than the individual driver means a correctly sized tip is always to hand, which is what stops a mismatched blade rounding out a recess leading to stripped screws.

Sets run from full workshop tool rolls down to precision and miniature screwdriver sets built for instrument, hobby and electronics work, covering the drive types an engineer meets across a project rather than leaving gaps a single driver cannot fill.

How Screwdriver Sets Work

A screwdriver converts hand rotation into torque at the fastener, so the quality of that conversion rests on how precisely the tip sits in the recess of the drive. A correctly matched tip contacts the drive faces across their full depth, sending applied force into the screw instead of lifting the driver out of it. That lifting is cam-out, the tendency of a tapered tip to ride up under load, which a graded set helps to prevent. 

Drive profiles differ because they solve different problems: slotted reaches into narrow electrical terminals, Phillips self-centres for speed but cams out deliberately at high torque, Pozidriv adds ribs to resist that cam-out so the two must never be substituted, Torx spreads load over six lobes, hex suits cap head socket screws, while Tri-Point and Pentalobe are security profiles restricting casual disassembly.

A field service engineer stripping a control panel may meet up to 5 different drive sizes when working on its enclosure and resulting repair. One set covers the teardown then the rebuild without a return trip to the van or workshop. Sets including a 3 mm phase tester let the same engineer confirm if a terminall is dead before touching it, adding an extra layer of engineering safety.

What Materials Screwdriver Sets Are Made From

Accu's Wera screwdriver sets are built from high-performance engineering materials, selected for torsional strength at the tip and grip security at the handle:

• Steel - CrV (6150): A high-grade alloy with strong resistance to torsional deformation, so tips hold their profile under repeated loading rather than rounding off.
• Steel - Chromoly: Offers high toughness and resistance to shock loading, suited to drivers seeing impact or sudden torque reversal.
• Plastic - TP: Used in the two-part Wera handle moulding, where hard zones let the fingers spin the driver during run-down while softer rubberised zones grip the palm for high-torque tightening.

What Size and Type Screwdriver of Sets Are Available

Accu's range of screwdriver sets is available in a variety of drive types and graded tip sizes to accommodate a range of assembly, maintenance and electronics needs:

• Drive Type: Slotted, Phillips, Pozidriv, Torx, Hex, Tri-Point and Pentalobe.
• Phillips Tip Size: PH1 to PH2.
• Pozidriv Tip Size: PZ1 to PZ2.
• Torx Tip Size: T15 to T25.
• Slotted Blade Width: 2.5 mm to 7 mm.
• Set Type: Fixed blade, precision, miniature and multi-bit.

Slotted with Phillips covers general-purpose work, while Phillips, Pozidriv and slotted combinations suit equipment carrying all three recesses. Specialist sets add Tri-Point and Pentalobe for consumer electronics and security-fastened devices; selected sets include a 3 mm phase tester for verifying whether a circuit is live.

FAQs

Q: What is the best screwdriver set to buy?

A: The best set is the one matching the fasteners you actually work on. List the drive profiles you meet weekly, then choose between fixed blades, which are faster and stronger under torque, or multi-bit sets, which cover more profiles in less space. Precision sets suit instrument work only. Weigh the warranty last.

Q: What is a good quality screwdriver set?

A: Quality shows in three places. The blade steel should be a hardened high-grade alloy such as chromium-vanadium or chromium-molybdenum, holding tip geometry through thousands of engagements. Tip machining should be tight enough for full recess contact, preventing cam-out. The handle should combine hard zones for speed with softer zones for torque.

Q: Which screwdriver brand is best?

A: Judge brands on specification rather than reputation: blade steel grade, heat treatment, tip tolerance, handle ergonomics, drive coverage and warranty terms. Accu stocks Wera screwdriver sets, built with vacuum ice-hardened chromium-vanadium and chromium-molybdenum blades, multi-component Kraftform handles and a lifetime warranty. Those specifications are what any comparison should turn on.

Q: How to choose a screwdriver set?

A: Work through four questions. Which drive types do your fasteners use? Are the tip sizes graded across the range you need, or does the set skip one you hit weekly? Does the format suit the work, fixed blade or multi-bit? Does the specification justify the price in steel, tolerance, handle and warranty?
