JIS stands for Japanese Industrial Standard. A JIS screwdriver bit has a cross‑head profile designed for fasteners found on many Japanese motorcycles, cars, bicycles, and equipment. You’ll typically see sizes #1, #2, and #3, often with a 1/4‑inch hex shank for use in common bit holders.

• Applications: maintenance and repairs on Japanese-made gear.
• Options: short or long bits, manual and impact-ready versions.
• Materials: durable S2 steel and magnetic tips are common.
• Benefits: a closer fit in JIS screws can reduce cam-out and wear.

Browse sets to match the sizes and lengths your project needs.

JIS and Phillips are different cross‑head standards, so the bit geometry isn’t identical. On fasteners made to JIS, a JIS bit can seat more fully, which may help reduce cam‑out and preserve the screw head. On Phillips‑standard screws, a Phillips bit generally provides the intended fit.

• Use JIS bits for Japanese equipment where JIS screws are common.
• Use Phillips bits for screws marked or specified as PH.
• Many JIS bits can drive Phillips screws, but fit can vary.
• Choose sizes (#1, #2, #3) to match the fastener and tool.

Matching the standard to the screw helps improve results.

PH2 refers to a Phillips #2 driver size, while JIS #2 is the Japanese Industrial Standard’s #2 cross‑head size. They’re similar in overall scale but shaped differently, so the seating feel can differ.

• For screws specified as PH2, a Phillips #2 bit is appropriate.
• For Japanese motorcycles, bicycles, and equipment, JIS #2 is commonly used.
• Both are available with 1/4‑inch hex shanks for easy compatibility.
• If unsure, test the fit gently and choose the bit that seats cleanly without wobble.

Select the size and bit length (short or long) that suits your reach.

Pozidriv and JIS are distinct standards. Pozidriv is a variation of the cross‑head with extra ribs and is common on some European fasteners. JIS is the Japanese Industrial Standard cross‑head used on many Japanese vehicles and equipment.

• Identification: Pozidriv screws often show additional tick marks on the head; JIS looks like a standard cross.
• Fit: Using the matching bit can help reduce slippage and wear.
• Availability: JIS bits come in #1, #2, #3 sizes and various lengths.
• Compatibility: Both are typically offered with 1/4‑inch hex shanks.

Check your fastener type and choose the bit standard accordingly.

Most motorcycle and bicycle jobs use a mix of JIS #1, #2, and #3. The exact size depends on the fastener head and location.

• #1: smaller controls, brackets, and trim pieces.
• #2: common for body panels and general assemblies.
• #3: larger, higher‑torque fasteners.
• Length: 35mm bits are compact; 50mm offer extra reach.
• Tools: 1/4‑inch hex shanks fit standard bit holders; impact‑ready options are available for tougher tasks.

Compare the bit to the screw head and choose the size that seats snugly. When in doubt, consult your owner’s manual.
