SAE Hex Key 5/16

The Wiha Tools 33486 is a single SAE hex key with a 5/16 inch tip size and an overall length of 5 57/64 inches. It is made from CRM-72 steel with a black oxide finish for corrosion protection. The tool features a plain plastic handle with a red grip area. It is designed for professionals who frequently tighten or loosen hex fasteners on job sites.

Capacity and leverage

The long arm provides increased leverage for working with larger bolts and nuts where extra torque is helpful. The fixed 5/16 inch tip limits use to that specific fastener size. It cannot accommodate metric fasteners or other SAE sizes without additional tools. The key runs out of utility when the fastener head is stripped, recessed beyond reach, or requires a different drive profile.

Thermals noise and power

As a manual hand tool, it generates no operational heat, produces no noise, and draws no electrical power. The black oxide finish resists surface corrosion during storage and use. The plastic handle insulates the hand from cold metal in low temperatures. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item

Will the 5/16" tip fit the same SAE fasteners as my older hex keys?

Yes, the 5/16" SAE tip matches standard fractional fasteners so it works with the same bolts and nuts as your existing SAE hex keys.

How can I confirm the CRM-72 steel key is performing correctly after first use?

The black oxide finish should show no rounding on the 5/16" tip and the long arm should deliver smooth leverage without flex when seating or breaking loose a fastener.

Does the 33486 come with any extra bits or a holder, or is it just the single key?

The package contains only the single 5/16" plain hex key with its red grip handle; no bits, holders or additional keys are included.
