Starrett Force Accessories
Product Overview
Starrett offers a wide variety of grips, fixtures, and platens designed to secure specimens for repeatable force measurement. From high-capacity wedge-action grips for metals to delicate pneumatic fixtures for medical films, these accessories ensure that the force applied is perfectly axial and that the specimen remains secure throughout the test cycle. By utilizing a standardized 15.9mm (5/8″) or 31.8mm (1.25″) clevis mounting system, these fixtures can be swapped in seconds, allowing a single Starrett test stand to transition seamlessly between diverse applications.
Whether you are performing 90-degree peel tests on adhesives or high-load compression on building materials, the right fixture is critical to data integrity. Starrett’s accessories are engineered for industrial durability, featuring hardened steel or lightweight anodized aluminum construction to minimize deflection and maximize the life of your testing system.
Precision Test Fixtures
Starrett offers a full range of test fixtures and grips for a range of applications. Test fixtures are compatible with all Starrett test frames.
Button Head Fixtures: Ideal for terminal and crimp strength testing, providing a secure “Better Way” to validate wire and fastener integrity.
Compression Cages: Create a stable, high-load environment for crushing tests, lowering risk by containing specimens during high-force failures.
Flexural Fixtures: Allow for accurate 3-point and 4-point bend testing to determine the stiffness and breakage limits of brittle materials.
Peel Fixtures: Specifically designed to measure the adhesive strength of tapes and films at constant angles, improving quality in packaging and labeling.
Pneumatic Fixtures: Use automated air pressure for fast, repeatable clamping, raising efficiency by reducing operator fatigue in high-volume production.
Roller Grips: Utilize a self-tightening cam action that is perfect for materials like rubber that thin out as they are stretched.
Scissor Grips: Feature a large opening and self-tightening action, making them the “Better Way” to secure oversized or irregular samples.
Vice-Action Grips: Offer a versatile, manual clamping solution that is easy to adjust for a wide variety of general-purpose tension tests.
Wedge-Action Grips: Automatically increase clamping force as the axial load grows, preventing specimen “pull-out” on high-strength composites and alloys.

Specimen Preparation & Analysis
ASTM/ISO Specimen Dies: Ensure perfectly consistent sample dimensions for standards like ASTM D-412 and D-638, which is vital for achieving repeatable, audit-ready data.
Contact-Type Extensometers: Provide ultra-precise strain measurement directly from the specimen surface, essential for calculating Young’s Modulus and fulfilling L3 material analysis requirements.
Self-Aligning Platens: Feature a spherical seat that adjusts for non-parallel samples, ensuring a uniform load distribution and improving quality in compression testing.
