Spanner Screw

Spanner screws designed for tightening with compatible spanner wrenches in mechanical tasks.

Introduction

Spanner screws feature two holes or slots on the head that match spanner wrenches for secure fastening where standard drivers won’t reach. The low-profile head sits flush in confined spaces such as machinery panels or automotive trim. Hardened steel construction resists rounding under torque, and corrosion-resistant finishes extend service life. Available in metric and imperial sizes, each screw provides consistent clamping force without marring surrounding surfaces.

  • Drive style: two-hole or slotted for spanner engagement
  • Material: hardened alloy steel with zinc or black oxide coating
  • Thread options: coarse or fine pitch in multiple diameters

Select the spanner screw size that matches embly needs.

FAQs

Use a two-pin spanner wrench or hook spanner sized to the screw’s hole spacing.

Yes, as long as the holes remain undamaged and threads are not stripped during removal.

Follow the equipment manual; spanner screws usually seat with standard hand torque unless stated otherwise.

Only if clearance allows; the low-profile head of a spanner screw is often chosen for flush fit.

Electronics enclosures, automotive interior panels, and precision machinery where tamper resistance or low clearance matters.
