Four piece measurement tool set designed for reliable precision in automotive maintenance and metalworking. Key benefits - Valve setting tool: wear resistant and rugged for harsh conditions; enables accurate valve clearance adjustment. - Stainless steel metal thickness gauge: high durability with stainless steel construction for long service life and repeatable thickness readings. - Pull gauge (Ziehlehre): compact, portable design for easy storage and transport of the gauge. - Feeler gauge: high precision for gaps and clearances; ideal for maintenance and repairs that require accuracy. Typical applications - Engine valve service: use the valve setting tool to set valve clearances and verify with the feeler gauge. - In shop or on site thickness checks: measure metal sheet or component thickness with the stainless steel thickness gauge. - General automotive maintenance: the compact pull gauge supports quick checks of small components and gaps during repairs.
