100-piece screwdriver bit set FERVI 0640 for workshop repairs

The 100-piece screwdriver bit set FERVI 0640 gathers most bit profiles used in daily repair work. The range covers Phillips, Pozidriv, slotted, Torx, hex, square, spline and clutch drives. Each family comes in several consecutive sizes, so a missing step rarely halts a job. Size 2 Phillips and size 2 Pozidriv are supplied in five pieces each.

A 1/4 inch extension bar ships with the kit for screws sitting deep or behind obstacles. All bits are stored in a hard plastic case with one slot per bit. The layout makes a missing piece visible at a glance during an end-of-shift check. Metric and inch sizes sit side by side, which helps on imported machinery. Tamper-resistant work is covered by pierced Torx and pierced hex bits.

Case and bit layout

The hard plastic case opens to show every row of bits at once. Each cavity holds a single bit, so sizes do not get mixed during a job. Empty cavities show immediately which bit is still on the bench. The closed case keeps the set together when moving between work positions or storing it in a tool cabinet drawer.

• Hard plastic case holding all 100 pieces
• One dedicated slot per bit
• Visual check for missing or misplaced bits
• Portable for field maintenance calls

Common applications

The kit suits mechanical repair, machine maintenance and small assembly work. Pierced Torx and pierced hex bits match security screws on electronics, office machines, motorcycles and household appliances. Slotted, Phillips and Pozidriv bits handle most screws found in electrical panels and furniture. The inch hex range supports machinery built to British and American sizing. The 1/4 inch extension bar reaches screws recessed inside housings or covers.

Working notes

Match the bit size to the screw recess to avoid rounding the head. Fit the bit into a 1/4 inch hex holder, a bit driver or a power screwdriver. Return each bit to its own cavity after use so the set stays complete. Wipe oil and grease off the bit before storage to limit slipping on the next job.
