Wiha Tools 20131 Open End Wrench SAE 1/4 in

SKU CH-RV6Z-WDE3K

An insulated, single-end open-end wrench with a high-visibility coating for 1/4 inch SAE fasteners

  • Precise fit for 1/4 in SAE fasteners
  • 10 degree offset clears tight spaces
  • Alloy steel construction resists wear
  • High-visibility coating speeds identification
  • Insulated single-end design adds safety

Single-End 1/4 in Open-End Wrench

This Wiha 20131 open-end wrench is a single-end SAE tool sized at 1/4 in for technicians who need a precise fit on small fasteners. The alloy-steel body carries a high-visibility coating and insulated handle for identification and electrical safety. It suits professional maintenance and assembly tasks where a single fixed size is preferred over an adjustable alternative.

Insulated High-Visibility Alloy Steel

The decisive specification is the insulated, high-visibility alloy-steel construction that meets safety and visibility requirements on live or cluttered work sites. The 10-degree head angle and rounded single-end profile allow engagement in restricted clearance without damaging fastener corners. Buyers who need a non-insulated or double-ended wrench should select a different model.

One-Piece Design Requires Correct Sizing

Installation is immediate because the one-piece wrench has no moving parts or adjustment mechanism. The only common error is selecting the wrong SAE size, as the 1/4 in head cannot be adapted to other dimensions. Verify the fastener size before purchase to avoid mismatched fit.

Questions about this item

What does the 10-degree head angle do on the 20131 wrench?

The 10-degree offset angles the open end away from the handle, giving clearance for fingers or nearby obstructions when turning a fastener.

How does the SAE sizing and single-end design affect use?

The wrench fits 1/4-inch SAE fasteners only, and the single-end layout means one fixed head without a second size on the opposite side.

What clearance is needed to fit the 20131 in a tool holder?

The overall length is 3 3/8 inches, so the storage slot or organiser pocket must accommodate at least that length.
