Stainless Steel Spring Lock Washers
Split Spring Washers for Bolted Connections, Machinery & Industrial Assembly
Stainless Steel Spring Lock Washers are single-coil split washers with helical free-state geometry and rectangular spring section. Installed beneath a bolt head, screw head or nut, they compress as the joint is tightened and provide traditional elastic washer action.
Product Overview
A Split Spring Washer is a single circular coil with one split, axially offset ends and rectangular section. It is fitted beneath a bolt head, screw head or nut in suitable machinery, fabrication and equipment joints.
As tightening progresses, free height h is compressed and the washer develops elastic reaction. This traditional action can help maintain contact in appropriate joints, but it is not a guaranteed anti-loosening or universal high-vibration locking solution.
Buyers should specify nominal fastener size, Form A or B where relevant, d1, d2, section width b, thickness s, free height h, material, finish, quantity and drawing or sample.

Frequently Asked Questions
What is a Split Spring Lock Washer?
A single-coil split washer with helical free-state geometry that compresses as a joint is tightened.
Is DIN 127 still a current standard?
No. DIN 127 is withdrawn, but remains widely used in international purchasing; VALTOR supplies traditional DIN 127 dimensions or customer specifications.
What is the difference between DIN 127 Form A and Form B?
They use different split/end geometry; specify the exact form required by the drawing or assembly.
Do Spring Lock Washers completely prevent bolt loosening?
No. They provide traditional elastic action, not universal high-vibration locking; joint design determines whether another method is needed.
Can VALTOR supply 304 and 316 Stainless Steel Spring Washers?
Yes. 304/A2 and 316/A4 versions plus custom dimensions are available according to inquiry.
