This is useful when you cannot align the wrench straight with the bolt. The flat-end tip provides full hex contact and is recommended for applying maximum torque during final tightening, as the ball-end can slip under high load.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich size should I choose for bicycle maintenance?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe most commonly used sizes for bicycle work are 4mm, 5mm, and 6mm — covering stem bolts, brake caliper bolts, and derailleur clamp bolts.

The ball-end tip contacts only a portion of the hex socket faces when used at an angle, which reduces the effective torque transfer and increases the risk of rounding the fastener.

The hardened alloy steel construction is harder than both stainless steel and aluminum fasteners, so the wrench tip will not deform before the fastener does.
